Every reader and every database meets your paper through its title. It has to say what you studied, in whom, and how, without claiming more than the study shows.
What a title has to do
Every reader of your paper meets the title first, and so does every database that indexes it. The title has to do its work before anyone reaches your abstract.
The ICMJE Recommendations describe the job precisely: the title "provides a distilled description of the complete article and should include information that, along with the abstract, will make electronic retrieval of the article sensitive and specific."
Sensitive means that someone searching for your topic finds your paper. Specific means it does not turn up in searches it cannot answer, where it only wastes a reader's click.
In PubMed, a search tagged [ti] matches only words in the title, and [tiab] matches words in the title, abstract and author keywords. PubMed's help pages also warn that filters relying on MEDLINE indexing, such as article type filters, may exclude citations that have not yet completed indexing. A text search can match only the words you actually chose.
Human readers need the same thing, whether they are editors or clinicians scanning search results. The test: could someone who reads only your title decide correctly whether your paper is relevant to them? If they would have to open the abstract to learn the population or design, the title is not finished.
Build the title from its parts
Most medical research titles are assembled from the same few pieces:
- Topic: the intervention, exposure, test or condition at the centre of the study
- Outcome: what you measured
- Population: who was studied, plus the setting only if it matters
- Design: how you studied it
- Comparator: only when a reader cannot infer it
The AMA Manual of Style team reduces the core to a formula on its AMA Style Insider blog: the key variable or variables measured, plus the individuals or condition studied.
Here is how that works on a hypothetical study, invented for illustration: a cluster randomised trial of pharmacist-led medication review for older adults, with unplanned hospital admission as the outcome.
- Medication review in elderly patients. Topic only: no outcome, no design, and vague about who was studied.
- Pharmacist-led medication review and unplanned hospital admissions in older adults. Intervention, outcome and population are now all searchable.
- Pharmacist-led medication review and unplanned hospital admissions in older adults: a cluster randomised trial. The design tells a reader what kind of evidence to expect.
Notice what never made it in: "A study of", the usual-care comparator, the region and the recruitment years. All of that belongs in the abstract.
Name the study design where guidelines expect it
The ICMJE Recommendations note that reporting guidelines recommend, and some journals require, design information in the title, "particularly important for randomized trials and systematic reviews and meta-analyses." The main guidelines differ in how firmly they ask:
| Study type | Reporting guideline | What it asks for |
|---|---|---|
| Randomised trial | CONSORT 2025 | Identification as a randomised trial in the title |
| Systematic review | PRISMA 2020 | Identification of the report as a systematic review in the title |
| Observational study | STROBE | The study design, in a commonly used term, in the title or the abstract |
| Diagnostic accuracy study | STARD 2015 | Identification as a diagnostic accuracy study, with at least one accuracy measure, in the title or abstract |
| Case report | CARE | The diagnosis or intervention of primary focus, followed by the words "case report" |
Where a guideline allows either, house style decides, and placement varies. PLOS ONE asks for the design in the subtitle for clinical trials, systematic reviews and meta-analyses. AMA style guidance accepts subtitles such as "A Randomized Clinical Trial" for trials and reviews, but says observational studies should generally avoid subtitles.
Use the design term people search for, such as "cohort study" or "systematic review and meta-analysis", in the journal's spelling of randomised or randomized. And check the current checklist version before you cite it: CONSORT 2025 supersedes CONSORT 2010, and the EQUATOR Network library lists current guidelines by study type.
Descriptive, declarative or question titles
Here is the same hypothetical trial titled three ways. The "result" in the declarative version is invented for this example.
| Style | Example | What it does |
|---|---|---|
| Descriptive (indicative) | Pharmacist-led medication review and unplanned hospital admissions in older adults: a cluster randomised trial | Says what was studied and how |
| Declarative (informative) | Pharmacist-led medication review reduces unplanned hospital admissions in older adults: a cluster randomised trial | States the finding |
| Question | Does pharmacist-led medication review reduce unplanned hospital admissions in older adults? | Poses the research question |
"Informative" is simply another name for declarative. Wager, Altman, Simera and Toma define declarative (or informative) titles as those that "state the study findings", and descriptive (or indicative) titles as those that describe the study topic and design.
Journals disagree. Wager and colleagues note that many journals prohibit declarative titles while a few encourage or even require them. AMA style guidance advises against revealing results in the title, including declarative statements such as "X is associated with Y".
The evidence is thin. In a randomised trial by Wager's group, students and doctors read a fictitious trial abstract under either a declarative or a descriptive title, and the authors found no evidence that the declarative title changed readers' confidence in the conclusions. They tested abstracts, not full papers, and limit their reassurance to reports of randomised trials. Citation studies are observational: Paiva and colleagues (Clinics, 2012) linked short titles presenting results to more citations, and Jamali and Nikzad (Scientometrics, 2011) found PLOS articles with question titles tended to be downloaded more but cited less.
Use these decision rules:
- Follow the journal first. Read the instructions, then look at research titles in a few recent issues. If every one is descriptive, expect a declarative title to be changed.
- Use a declarative title only when the design can carry the claim. The primary outcome of a randomised trial may; a subgroup or pilot result rarely can.
- Keep causal verbs out of observational titles. "Reduces", "prevents" and "improves" claim more than a cohort or cross-sectional design can show.
- Use a question only if the journal accepts it and the paper answers it.
Length: say it once, then stop
There is no universal limit. The ICMJE Recommendations set a length only for the short title, and note that submission systems may restrict title characters. JAMA Network editors aim for research article main titles of no more than 100 characters with spaces. Other journals count differently, so check whether the limit is in characters or words.
The research leans towards shorter titles, with caveats. Letchford, Moat and Preis (Royal Society Open Science, 2015) found that journals publishing papers with shorter titles received more citations per paper, but could not establish cause. One possibility they raise is that high-impact journals restrict title length.
Cut words that carry no information:
- "A study of", "An investigation into", "Report of"
- "Effect of" or "Association of" as opening words, which AMA style guidance suggests skipping
- A comparator the reader can infer
- Location and study years, unless they are the point of the study
- "Novel", "new" and "first"
A worked cut, again on an illustrative title:
Before (207 characters): A retrospective cohort study investigating the association of long-term proton pump inhibitor use with the risk of hip fracture among postmenopausal women attending primary care clinics between 2015 and 2020
After (111 characters): Long-term proton pump inhibitor use and hip fracture risk in postmenopausal women: a retrospective cohort study
The main title before the colon is 81 characters and still says what was studied. That matters: AMA style guidance notes that, depending on a journal's digital practices, only the main title may appear in a Google search result. Cover the subtitle; if the rest does not say what you studied, rewrite it.
Words and habits that cost you readers
| Habit | Problem | Fix |
|---|---|---|
| Specialist abbreviations | Readers outside your subspecialty cannot decode them, and the same letters mean different things in different fields | Spell the term out; check which abbreviations the journal accepts |
| A trial acronym as the main title | Tells nothing to anyone who does not already know the trial | Name the intervention and outcome; put the trial name in a subtitle where the journal allows |
| "Novel", "first", "breakthrough" | Carries no information | Say what is new in the abstract, in concrete terms |
| Puns and wordplay | Searches match terms, not jokes, and wordplay can be lost on readers outside your field or language | Put the searchable terms in the main title |
| A title that promises more than the paper delivers | Reviewers and readers notice the gap | Recheck the title against your conclusions after the last revision |
If a reviewer says your conclusions go beyond your data, check the title as well as the discussion. An overstated title repeats the problem in every database record and reference list.
The short title, or running head
Some journals ask for a second, shorter title on the title page or in the submission system. It may be called a short title, running title or running head, and some journals print it at the top of the article's pages. The ICMJE Recommendations say it is usually no more than 40 characters, including letters and spaces, but journals set their own limits. It never replaces the full title, which is what appears in the citation.
To write one, keep the topic and outcome and drop the design, population and qualifiers. For the hypothetical trial above, Pharmacist review and admissions is 32 characters. Avoid squeezing a term into an abbreviation to fit unless the journal accepts it.
A title check before you submit
Write a working title early, but settle the final one after the abstract and conclusions are finished, because the title has to match what the paper concludes. Then check:
- Topic, outcome and population named in plain words
- Study design named where the reporting guideline and journal expect it
- Style matches research titles in recent issues of the target journal
- No causal verb unless the design supports the claim
- Within the journal's length limit, counted the way the journal counts
- Main title makes sense with the subtitle covered
- Short title within its limit
- A PubMed [tiab] search on your key terms shows the words related papers use, and your title uses them too
- Identical title on the title page, manuscript, submission form and cover letter
That last point slips easily after several rounds of edits; our guide to what editors look for in a cover letter recommends giving the full title exactly as it appears on your title page. For the rest of the package, work through our manuscript submission checklist.
If you spend extra time anywhere, spend it on the first test: read only your title and ask whether the right reader would know to open the paper. The Directive Publications For Authors page links to its author guidelines and article type definitions, so you can check how to prepare your manuscript before you submit.
Frequently asked questions
Should a research paper title include the study design?
For randomised trials and systematic reviews, usually yes. The ICMJE Recommendations note that reporting guidelines recommend design information in the title and some journals require it, and CONSORT 2025 and PRISMA 2020 both ask for the design to be identified in the title. For observational and diagnostic accuracy studies, STROBE and STARD accept the design in the title or the abstract, so follow the target journal's style.
Is it acceptable to use a question as a paper title?
Some journals accept question titles, but AMA style guidance used at the JAMA Network advises against them for research reports because they signal uncertainty. One analysis of PLOS articles found that question titles tended to be downloaded more but cited less, although that is an association rather than proof of cause. If your paper gives a clear answer, a descriptive title usually serves readers better.
Should abbreviations be avoided in a title?
In most cases, yes. Readers outside your subspecialty may not recognise an abbreviation, and the same letters can mean different things in different fields. PLOS ONE, for example, asks authors to avoid specialist abbreviations in titles where possible. Some journals accept a few very widely known abbreviations, so check the instructions for authors before you use one.
What is the difference between a title and a running head?
The title is the full name of your article, the one that appears in the citation and in database records. A running head, also called a short title or running title, is a shortened version that some journals ask for to print at the top of pages or to enter in the submission system. The ICMJE Recommendations note that it is usually no more than 40 characters, including letters and spaces, but check the journal's own limit.
Does the title affect how often a paper is cited?
Several observational studies have linked title features to citations, including shorter titles, titles that state results, and titles that are not phrased as questions. None of them can separate the effect of the title from the journal, the field and the quality of the work, so treat the findings as suggestive. The dependable benefit of a clear title is that the right readers can find the paper and tell quickly that it is relevant to them.
