One for All

If you’re eating candy, it’s “3 Musketeers.”

If you’re reading about the friends of d’Artagnan, it’s The Three Musketeers.

Given that JAMA Network publications are technical instead of literary (A Piece of My Mind and Poetry notwithstanding), we would fall on the candy side of the divide between using numerals and using words (whether candy is technical is a discussion for another day).

The online abstract to Chapter 18.0 in the AMA Manual of Style, Numbers and Percentages, raises “the difficult question of when to use numerals and when to use words, and how to combine the two.” Note the tidy example of spelling a number as a noun. This difficulty is a factor in what I see as numeral inflation in the form of encroaching “1” use.

One of the most obvious places for numeral use is in identifying study populations.

For example, take this hypothetical Delphi consensus group: 5 physicians, 4 nurse practitioners, 3 patient advocates, 2 patient caregivers, and 1 health system leader.

One of the most obvious places for spelled number use is in idiomatic phrasing or in parts of speech. Section 18.2.3, Accepted Usage, advises using words “in circumstances in which use of the numeral would place an unintended emphasis on precise quantity.” When a number appears in text, what is the cutoff point between intended and unintended emphasis?

The manual suggests that “common sense” plays a role in editorial judgment, but one person’s “common sense” is another person’s “thanks anyway.”

As examples of avoiding unintended emphasis on quantity, the style manual lists “one-time variables,” “in one recent case,” and “has become one of the dominant topics.” However, in current publications you will find encroaching “1” use in various “1-time” constructions, the phrase “in 1 recent analysis,” and the wording “has become 1 of the leading reasons.”

How about these uses of encroaching 1?

  • “At least 1 moderate event.”
  • “In 1 large health system.”
  • “More than 1 time zone.”

Numeral use would seem to be justified by the idea that a moderate event, a large heath system, and a time zone are being counted.

Section 18.2.2 advises that we should spell “one” used as a pronoun or a noun, and these 1s are part of a noun phrase as the object of the prepositions “at least,” “in,” and “more than.”

I am “all for one.” It can be a relief to have an automatic edit to make in the name of upholding style, but many of us are not “one for all”—even in cases sanctioned by Accepted Usage. Not every “one” that seems countable should be “1,” and I offer this observation not to get editors into the weeds (an occupational hazard) but rather to help them avoid reflexive editing.

Can JAMA Network Authors Use Generative Artificial Intelligence to Create Content?

Jennifer Sakhnovsky, MA, JAMA Network

The short answer is yes, but with a caveat: transparency is key. It is no secret that generative artificial intelligence (AI) models can create various types of content, including text, images, audio, and video. However, people’s feelings about using these tools in scientific research are mixed, with some academics showing concern and others embracing the new technology.

Regardless of personal opinion, people are using these tools—a 2023 Nature survey of more than 1600 scientists reported that nearly 30% reported using generative AI tools to assist with writing manuscripts.1 As 2023 began, many research articles already listed the generative AI tool ChatGPT as an author.2 By October of the same year, 87 of the 100 highest-ranked scientific journals saw the need to publish online guidance for authors on generative AI use for content creation at their publications.3

JAMA and the specialty journals in the JAMA Network were among those that provided online guidance, encouraging authors, reviewers, and editors to be transparent, responsible, and follow AI best practices in medical and scientific publishing. Importantly, the guidelines noted that “nonhuman artificial intelligence, language models, machine learning, or similar technologies do not qualify for authorship.”4 More information on ethical and legal considerations can be found in chapter 5.1.12 of the AMA Manual of Style.

If authors choose to use AI tools to create content or assist with manuscript creation, they must disclose such use in the Methods or Acknowledgements section of the article. The following example, found in chapter 3.15.13 of the AMA Manual of Style, can be used as an acknowledgment for an article that uses generative AI:

The authors acknowledge using ChatGPT (GPT-3.5, OpenAI) for text editing to improve the fluency of the English language in the preparation of this manuscript on September 15, 2023. The authors affirm that the original intent and meaning of the content remain unaltered during editing and that ChatGPT had no involvement in shaping the intellectual content of this work. The authors assume full responsibility for upholding the integrity of the content presented in this manuscript.

As presented in this example, the following information must be included in the disclosure of AI use for content generation:

  • Name of the AI software platform, program, or tool;
  • Version and extension numbers;
  • Manufacturer;
  • Date(s) of use; and
  • A brief description of how the AI was used and on what portions of the manuscript or content.

In addition to the above considerations, authors should provide the following additional information if AI was used in the study:

  • Prompt(s) used, their sequence, and any revisions;
  • Institutional review board/ethics review, approval, waiver, or exemption;
  • Methods or analyses included to address and manage AI-related bias and inaccuracy of AI-generated content; and
  • Adherence to a relevant reporting guideline if followed.

These guidelines emphasize accountability and human oversight when AI is used in medical publishing. To assist authors with adhering to new policies regarding AI, the JAMA Network’s automated manuscript submission system asks all authors whether AI was used for content creation.5 If AI tools were used to generate creative content (noncreative content, such as basic grammar and spelling checks, does not need to be disclosed), authors must provide specific information about their use and take responsibility for the integrity of the AI tools’ outputs.

JAMA Network authors are also asked to be aware of inputting identifiable patient information into an AI model, as well as potential copyright and intellectual property concerns. Limitations of AI tools should be included in an article’s Discussion section, including potential inaccuracies or biases, and, ideally, how these have been managed by the authors.

The JAMA Network also encourages authors to consult relevant EQUATOR guidelines (https://www.equator-network.org) depending on the type of study and AI use,4 including the following:

  • Reporting guidelines for clinical trial reports for interventions involving artificial intelligence (CONSORT-AI);
  • Guidelines for clinical trial protocols for interventions involving artificial intelligence (SPIRIT-AI);
  • Minimum information about clinical artificial intelligence modeling (MI-CLAIM);
  • Checklist for Artificial Intelligence in Medical Imaging (CLAIM);
  • MINimum Information for Medical AI Reporting (MINIMAR) for developing reporting standards for AI in health care; and
  • Updated guidance for reporting clinical prediction models that use regression or machine learning methods (TRIPOD-AI).

At the time of writing this blog post, several reporting guidelines are under development by the EQUATOR Network, including the following:

As AI tools continue to gain momentum and develop rapidly, editorial leaders of scientific journals are wise to guide the responsible use of such tools. This guidance may—and likely will—evolve over time. Like other publishers, the JAMA Network has moved expediently to publish AI usage guidelines. As is true for the journal’s other style rules, authors who publish in JAMA and the JAMA Network specialty journals will be guided to follow these guidelines into the future.

Odds and Ends

Amanda Ehrhardt, MA, JAMA Network

Earlier this year, several small updates were made to the AMA Manual of Style that clarified some lingering questions that had left some editors potentially perplexed (or perhaps possibly puzzled!).

To Repeat or Not to Repeat?

The debate between the use of repeat vs repeated is no longer an existential crisis worthy of a Danish prince. Chapter 11.1 has been updated to indicate that these terms can be used interchangeably (just like Rosencranz and Guildenstern).

Game, Dataset, Match

One author serves up data in a data set. Another author swings their racket, sending data across the court in a dataset. So who won?

According to Chapter 11.3, author 2 can celebrate with strawberries and cream: dataset is now the preferred spelling.

A Sensitive Matter

To differentiate high-sensitivity troponin T from contemporary assays, it is now being reported in ng/L, which has been updated accordingly in chapter 17.5.

So please add these changes to the Homerian catalog already in your editor’s mind, as we know the evolution of style changes is always an odyssey!

Do Changes Actually Create Change?

Amanda Ehrhardt, MA, JAMA Network

Part of the purpose of the AMA Style Insider is to report on changes made in the AMA Manual of Style that aim to improve not only the editing process but also advance ethics and equity in medical publishing. Changes are not made arbitrarily but as a result of many experts building consensus on what represents best practices, and they’re made to create a widespread standard.

However, the manual can only release these standards to the world–what requires more follow up is whether the changes are actually implemented in publishing and how successful they are in creating new standards.

This year, in JAMA Network Open, several JAMA Network editors and staff published a cross-sectional study1 that examined race and ethnicity reporting across 3 JAMA Network journals before (January to March 2019 and May to July 2021) and after (January to March 2022) the implementation of the Updated Guidance on the Reporting of Race and Ethnicity in Medical and Science Journals2 in August 2021 (which was based on revisions made to 11.12.3 of the style guide).

Among the key takeaways were that the number of articles that reported race and ethnicity information for study participants increased by 10.4% from 2019 to 2022, more articles reported participants’ age or sex and gender, and the number of articles that defined categories included in the term “other” increased 58.1% from 2019 to 2022.

Additionally, the number of articles that listed racial and ethnic group categories by alphabetical order increased by 75.9% between 2021 and 2022, and there was a 24.1% increase in the number of articles that defined how race and ethnicity were determined.

Although this study had limitations (which are clearly stated in the article) and more improvement is needed, these results seem encouraging that AMA Style Manual updates are not made just to alter the day-to-day of editors across medical publishing, but to potentially create real and lasting change.

The AMA Garden of Hyphens

Timothy Gray, PhD, JAMA Network

If your professional life requires adherence to AMA style, you may have gotten lost in the weeds styling hyphenated compounds in titles. No capitalization after a hyphen if a prefix or a suffix, if both parts are considered a single word (requiring a field trip to Merriam-Webster), if the compound is temporary, or if the parts do not carry equal weight.

I have long wondered how parts of a compound carry weight, which isn’t to say that I don’t like the idea. As a practical suggestion, though, it lacks a little, uh, practicality.

If you think of a compound as an entity on its own, any word that may carry weight because of its particular part of speech loses that identity (and drops the weight!) when it gets pulled into that magical realm of a hyphenated compound (all adjectives all the time). So “Short-term Effects” and “Full-time Coverage” have always read as weird to me, especially if they have appeared near “Early-Onset Disease.”

How fitting, then, that the AMA Manual of Style has finally addressed the weed problem with hyphenation. No need to kill them. We can just get them out of our way. Let the weeds live happy lives in some other organization’s style manual.

The new guidance in 10.2.2 reads “In titles, subtitles, and text headings, capitalize both parts of a hyphenated compound.” Hence, “Short-Term Effects” and “Full-Time Coverage.” Take a look in the online manual for more information and other new style guidance.

Now when you review capitalization in titles with hyphenated compounds to align with AMA style, you needn’t make excursions to other sources. You can stay in the AMA garden without getting lost in the weeds.

Style vs Substance—Is There Room for Both?

Peter J. Olson, ELS, JAMA Network

There’s a scene in the film Pirates of the Caribbean: The Curse of the Black Pearl in which the heroine, Elizabeth, is taken captive by the infamous Captain Barbosa aboard his ship. In an attempt to negotiate her release, she invokes the Pirates Code, a set of rules to which she knows Barbosa is beholden. Barbosa initially appears to comply, then abruptly reneges. When Elizabeth protests his disregard for the Code, Barbosa defends his decision with a snide retort:

“The Code is more what you’d call guidelines than actual rules.”

His deviousness aside, the Captain has a point. As humans, we have an innate tendency to create rules with the intent of establishing order and certainty, yet those rules are occasionally subject to exceptions, inapplicability, and multiple interpretations. Try as we might, it’s virtually impossible to anticipate every possible scenario and account for it, which means there will be times when the rules we make for ourselves simply do not apply—and editorial style rules are no exception.

The question is: does style always supersede substance?

The AMA Manual of Style is a renowned and authoritative reference manual, and for good reason. It’s a meticulously crafted, oft-updated repository of linguistic and stylistic information steeped in authentic medical language and policy, and the guidance within its pages is critical to physicians, authors, and editors alike.

In that sense, the argument could be made that when it comes to the AMA Manual, style is substance. However, as editors, we at times find ourselves in scenarios in which adhering to a particular style point is akin to the proverbial placement of a square peg in a round hole. The gadget doesn’t quite fit into the device, and the results can be ugly. It’s those circumstances in which the absence of a peg may be preferable to the sight of a horribly splintered one.

What’s more, rules are almost always subject to change, and depending on the impetus behind an amendment, it can take the purveyors of a style manual weeks, months, even years to discuss and formulate a responsible and sustainable update before disseminating it to the manual’s users.

Take the topic of race and ethnicity language (Chapter 11.12.3), which continues to evolve at an unprecedentedly rapid pace—enough so that the requisite section in the AMA Manual was updated less than a year after the release of the 11th edition.1 Language and terms that may have been deemed acceptable just months previously may shift suddenly, and the intuitive and attentive editor may need to set aside current style guidelines to align with cultural and/or societal trends.

That said, style deviations should be made only after careful consideration of the potential ramifications, especially those involving reader perception. In other words: if you’re going to deviate from style, you’d better have a really good explanation ready.

Authors are often quick to point out style infractions in previously published material, either to defend their own infringements or to object to style-adherent edits (“If this author got to do it, why can’t I?”), and trivial or inexplicable noncompliance can undermine the authority of your style manual as well as your publication. If you can’t justify a style detour that goes beyond “I just thought it sounded better that way,” you probably shouldn’t take it.

Fictional though he may be, I expect that Captain Barbosa fully honors the Pirates Code—he is a pirate, after all. Yet even he knows to adapt the rules when necessary to achieve his goals. This is not to suggest that editors should swashbuckle their way through a manuscript, playing fast and loose with the style rules they’ve sworn to uphold. Those rules are there for a reason, and they wouldn’t exist if they didn’t almost always apply.

However, absolutism is fraught with its own perils, and the astute editor must be mindful of those rare situations in which a rule may need to be bent—or perhaps broken—for the greater good. And although there’s no single, comprehensive answer to the question of whether and when to sacrifice style for substance, if preserving the integrity of a publication is given precedence, the answers will at least be easier to identify.

Hawaiian Diacritics

Miriam Cintron, BA, JAMA Network

https://decolonialatlas.wordpress.com/2015/06/03/the-hawaiian-islands/

The islands of Hawaiʻi and its people have a culture rich in history, traditions, and the Native Hawaiian language.

Sadly, use of the Native Hawaiian language began to decline in 1896, when it was banned from schools just 3 years after the Hawaiian monarchy was overthrown.1 Without being taught in schools, the Native Hawaiian language became dangerously close to being completely forgotten. By the early 1980s, fewer than 50 children spoke the language.2

A resurgence in cultural pride and identity in the 1970s led to the resurgence of many Native Hawaiian cultural traditions, including the language.

With this in mind, the AMA Manual of Style strives to be accurate, fair, and respectful in reflecting the identities of individuals and groups. The Manual is adding 2 diacritical marks used in Native Hawaiian to the Accent Marks (Diacritics) section (chapter 12.2).

The okina (ʻ) is a glottal stop and the kahakō is a macron (ā) that lengthens and adds stress to the marked vowel.

The marks are used throughout the language, including in many of the names of the main Hawaiian islands (eg, Hawaiʻi, Kahoʻolawe, Kauaʻi, Lānaʻi, Molokaʻi, Niʻihau, and Oʻahu).

Note that Hawaiʻi has 2 official languages according to the state constitution: English and Hawaiian.3 “Hawaiian” is considered an English word, so it doesn’t take the okina.

Updated Guidance on Reporting Race and Ethnicity: Let’s Start With the Why

Kim Penelton Campbell, BS, JAMA Network

I have used many adjectives to describe myself, but I’ve never referred to myself as other. When teachers called my name during morning attendance, I responded by saying “Here.” I never said, “Invisible.”

In medical literature, the failure to fairly and respectfully recognize and include individuals of all races and ethnicities can severely adversely affect patients’ lives and the quality of care they receive. It can misinform clinicians. It can compromise the credibility of a journal.

This means that race and ethnicity data should be reported in a way that encourages fairness, equity, consistency, and clarity in medical and science journals.1

Changing the b in Black and the w in White to uppercase lettering when describing race is not about mere political correctness—these changes are part of a conscientious movement toward equitable delivery of health care services to all people.

The objective of this post is to emphasize that updated guidance about the reporting of race and ethnicity is important, not because the AMA Manual of Style says so, but because inattentiveness to these changes can contribute to unconscious bias and ultimately affect how patients are treated or unintentionally mistreated.

Bias, when unintentional, is not mitigated—it remains bias all the same. Unintentional bias can occur simply because the writer or editor is removed from the patient’s life experience. When the writer or editor is unaware, they may not recognize how insensitive wording can affect the reader.

Example: “Adherence to the prescribed medication was higher among White patients than among Blacks.”

Consequence: Does this mean that if you are White you are a patient but if you are Black you are nothing? What is a Black?

When a person is called a Black instead of a Black patient or a patient who is Black, the wording detracts from that person’s humanity.

Likewise, use of lowercase lettering for Black and White, as well as referring to people as minorities instead of as members of a racial or ethnic minority group, also diminishes their humanity. Stating race or ethnicity in noun form can be interpreted pejoratively and is akin to labeling patients by their disease (eg, the blind, schizophrenics, epileptics) instead of putting the individual first (eg, a person with schizophrenia).2 Other things that can be interpreted pejoratively and should be avoided are using the term mixed race, which can carry negative connotations, instead of multiracial or multiethnic, merging race and ethnicity with a virgule (ie, race/ethnicity) rather than recognizing the numerous subcategories within race and ethnicity with the term race and ethnicity, and using abbreviations for racial and ethnic terms. Although the writer or manuscript editor may not have intended to negatively portray a group of people, the potential effect on readers remains unchanged.

  • To potential authors, the absence of a single word can indicate that a journal is insensitive to the health care needs of a population of patients.
  • To clinicians with the same racial or ethnic background as the one negatively represented, this can promote the inference that the journal has no diversity on its editorial board or staff.
  • To a practicing physician, this language can translate to offensive or insensitive communication when speaking with a patient or a patient’s family member.
  • To a patient, this wording can indicate that the medical community views individuals from their racial or ethnic group as nonpersons—unseen, unconsidered, and uncared for.
  • For all of these individuals, this can deepen a sense of mistrust.

Language that excludes a racial or ethnic group can subtly influence a medical trainee to “unsee” the humanity in people who are from a different background. If their research and educational sources are written or edited without intercultural competence, the medical trainee may unintentionally miscommunicate or make incorrect assumptions about patients from other backgrounds. This breach can interfere with a clinician’s understanding of the patient and, in response, impede the patient’s trust in the clinician.

Among some patients from communities that have been medically underserved or ignored, information about medical mistreatment can transcend generations. Past miscommunication can lead to mistrust, which can then lead to fear.

A family may never forget that Grandma never came home from the hospital and that no clinician took the time to explain why. Although this family was made to feel invisible because of miscommunication, it is quite possible that the clinician intended no disrespect and had no knowledge of how the family was affected. A patient with a historic burden of oppression can potentially interpret disrespectful communication as an initial step down the road to medical abuse.

My godfather once expressed such fear. He was Black, the clinicians were White, and he had grown up in Mississippi during the 1940s. Although I asked, he refused to ever repeat details of what was said by these physicians many years ago. But decades later, when I was a teenager and a novice driver, my godmother phoned and urgently asked that I come to their home immediately to rush him to our local VA hospital.

On my arrival, she exclaimed, “I think he had a heart attack while gardening in the back yard!” I said, “I’ll call 911. The ambulance will get him there faster.” Then, she stopped me. She pleaded that I drive him there myself. As I rushed to his aid, she continued by telling me that he would die of fear if an ambulance came to their home. She told me that I must speak for him when we arrived, remain by his side, and do everything in my power to keep him calm.

He cried like a baby during the entire ride. He was afraid. He was humiliated about expressing fear in my presence. I did not know what to say. I just kept driving. My heart was broken.

This brief story is an example of deep-seated fear that some Black people experience in a health care setting, a fear that can only begin to be abated with a conscientious effort to ensure that language humanizes Black patients and patients from all racial and ethnic backgrounds.

How does one address suboptimal reporting on race and ethnicity?

  • First, follow the guidelines.
  • Second, write and edit with a raised antenna. Look for what is unsaid in addition to what is written on the page.
  • Try to interpret as if you are a person from a racial or ethnic group unlike your own. Think about how you would you feel as the subject or nonsubject of the article.
  • Consider how wording can be misinterpreted.
  • Consider how inattentiveness to detail can affect the health, safety, or life of someone who is misrepresented.
  • Edit responsibly, but without fear of respectfully questioning the author.

Remember: no one is invisible, and no one is other.

“Not everything that is faced can be changed, but nothing can be changed unless it is faced.”3

Abbreviating the Pandemic

If you’ve followed AMA style for at least the last several years, you may remember this big (welcome) announcement:

The companion abbreviation “AIDS” was given expansion-exempt status even before this with the 2007 publication of the 10th edition. It took some time for HIV to catch up.

Why did we decide that these 2 abbreviations no longer needed expansion? For one, they are ubiquitous, instantly recognizable (at least to English-reading audiences), and are long and cumbersome to write out in full.

After more than a year of publishing coronavirus-related content (JAMA’s first article was published in January 2020 by Fauci and colleagues), the AMA Manual committee has determined that COVID-19 and SARS-CoV-2 meet those same criteria to forgo expansion: ubiquity, familiarity, and cumbersome expansions.

  • Before: Protection against coronavirus disease 2019 (COVID-19) is mediated in large part by an immune response directed against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein.
  • After: Protection against COVID-19 is mediated in large part by an immune response directed against the SARS-CoV-2 spike protein.

While we all hope to soon have this pandemic in our collective rearview mirror, it is not likely that we will forget coronavirus disease 2019 or severe acute respiratory syndrome coronavirus 2.–Stacy Christiansen, Chair, AMA Manual of Style

Citing Online Journal Articles and Data from Repositories

The new edition of the AMA Manual of Style is here, and it has nearly 200 more pages on everything from reference citations to the ethical and legal issues associated with medical publishing.

If the amount of new content seems overwhelming, may I suggest starting with the basics?

I dove in by reviewing the References chapter.

Online Journal References

According to section 3.11.4, “Online Journal Articles, Preprints, and Manuscripts,” the basic components of an online journal reference haven’t changed: authors’ surnames and initials, the title of the article, abbreviated name of the journal, publication year, pagination, the date the article was accessed, and the DOI or URL.

What has changed it that the date accessed should now be listed before the DOI or URL, and the URL is not followed by a period.

Data Repositories

I’ve also edited a few articles that included an analysis of data sets from a repository. Data repositories serve as archives for isolated data sets that allow data to be mined for secondary use in research. In a situation like this, the data set used and the original source for the data should be cited.

In the example shown below, the information for the original source for the data is listed first, followed by the name of depository, the date of data deposit, and the DOI for the data set.

DeLeon TT, Almquist D, Kipp BR, et al. Data from: Assessment of clinical outcomes with immune checkpoint inhibitor therapy in melanoma patients with CDKN2A and TP53 pathogenic mutations. Dryad Digital Repository. Deposited March 12, 2020. doi:10.5061/dryad.m0cfxpp0g

Accurate references are a critical element of any published article. The updated guidelines on references ensure that readers are directed to additional resources for more information.—Juliet Orellana
