How to Publish a Clinical Research Paper: A Practical Guide

This guide is for doctors, nurses, allied health professionals, clinical trainees and PhD researchers who have completed a clinical study and now want to publish it. Clinical journals ask for more paperwork than most fields: a named reporting guideline, proof of ethics approval, a registration number for trials, conflict of interest forms and a tightly structured abstract. Missing any one of these is a common reason for a paper to be returned before review. Publish With Scopus is an independent UK consultancy. We are not a publisher or a journal, we have no affiliation with Scopus or Elsevier, and we do not guarantee acceptance or indexing.

Step 1: Pick the reporting guideline that fits your design

Reporting guidelines are checklists that tell readers and reviewers what a complete report of a given design contains. Many journals ask you to upload the completed checklist with page or line numbers. Choose the guideline from the design you actually used, not from the design you wish you had used.

• CONSORT for randomised controlled trials, including the participant flow diagram, randomisation method, allocation concealment, blinding and the prespecified primary outcome.
• STROBE for observational studies: cohort, case-control and cross-sectional designs. It asks for clear eligibility criteria, sources of data, handling of missing data and how confounders were addressed.
• CARE for case reports, with a timeline, diagnostic reasoning, follow-up and the patient perspective where possible.
• PRISMA for systematic reviews and meta-analyses, with the search strategy, the flow diagram and the risk of bias assessment. Protocol registration, for example in PROSPERO, is expected by many journals.

Other designs have their own guidelines, such as STARD for diagnostic accuracy studies and SRQR or COREQ for qualitative work. The EQUATOR Network keeps an up-to-date library. A practical habit is to open the checklist before you redraft, and to fill in the page numbers only once the text is final.

Step 2: Get ethics approval and trial registration in order

Editors want to see that the study was approved before it began and that participants gave informed consent, or that a committee formally waived consent. State the name of the approving committee, the reference number and the date in the methods section. For retrospective reviews of records, many institutions still require an approval or exemption letter, so keep a copy ready.

For clinical trials, most journals that follow ICMJE recommendations require registration in a public registry, such as ClinicalTrials.gov or the ISRCTN registry, before the first participant is enrolled. Put the registration number at the end of the abstract and in the methods. If your published protocol and your paper differ, for example in the primary outcome, explain the change and when it was made. Reviewers compare the two, and an unexplained switch damages trust quickly.

Step 3: Prepare the author declarations

Clinical journals usually ask for a set of statements, often as separate forms and as a short section at the end of the manuscript:

• Authorship and contributions, often in CRediT format, consistent with ICMJE authorship criteria.
• Competing interests for every author, usually on the ICMJE disclosure form, including industry payments and advisory roles.
• Funding sources and the role of the funder in design, analysis and the decision to publish.
• Data sharing statement, saying what data are available, to whom and under what conditions.
• Patient consent to publish, where any individual could be identified.
• Use of AI tools, if the journal asks, describing what was used and for which task.

Collect these from co-authors early. Waiting for a signed form from one busy co-author is one of the most common causes of delay at the submission stage.

Step 4: Write a structured abstract that stands on its own

Many readers and every editor see the abstract first, and most clinical journals use a structured format. A typical structure is Background or Objective, Methods, Results and Conclusions, with some journals adding Design, Setting, Participants, Interventions and Main Outcome Measures. Follow the journal's headings and word limit exactly.

• Objective: one sentence naming the question, the population and the comparison.
• Methods: design, setting, dates, eligibility, sample size and the primary outcome.
• Results: the main numbers with effect sizes and confidence intervals, not only p values. Report the primary outcome first.
• Conclusions: what the results support, stated no more strongly than the data allow.
• Registration: the trial or protocol registration number, where it applies.

Common problems include results that do not appear in the main text, a conclusion that goes beyond the data, and spin, such as stressing a secondary outcome when the primary outcome was not significant. If your abstract needs a careful outside edit, our abstract editing service works on the abstract, title and keywords together.

Step 5: Choose a journal that fits the study

Start with where the studies you cite were published, then check each candidate against a few points: does it publish your design and specialty, does it require a specific reporting guideline, what are the word and table limits, does it charge an article processing charge, and is it indexed where your institution needs it to be. Verify indexing on official sources such as the database's own title list, not on a journal's own badges.

Look at recent issues to see whether the journal publishes studies of your size and setting. A single-centre retrospective study may suit a specialty or regional journal better than a general medical journal, and that is a sound choice rather than a compromise. Watch for predatory warning signs such as promised fast acceptance or unclear peer review.

Step 6: Run a final pre-submission check

• The reporting checklist is complete, with page numbers that match the final file.
• The ethics statement, registration number and consent statement appear in the right places.
• Numbers in the abstract, tables and text agree with each other.
• All declarations are signed and uploaded for every author.
• The cover letter names the design, the main finding and why the journal's readers would care.
• Figures, tables and references follow the journal's format.

What a clinical publication support service does

A good support service does not write your findings for you or promise an outcome. It helps you present an existing study clearly and completely. Typical tasks are checking the manuscript against the right reporting guideline, editing language and structure, tightening the abstract, building a reasoned journal shortlist, preparing the cover letter and declarations, and helping with reviewer responses later. For the full service, see our clinical research publication support page. If you are writing up a single patient case, our case report publication support covers CARE and consent issues in more detail.

How we work with clinical authors:

• We agree a written scope first, so you know what will be done before work starts.
• Edits are delivered with tracked changes, so you can accept or reject each one.
• Nothing is submitted without the author's written approval.
• You stay the corresponding author and keep control of the paper.

We have supported 500+ researchers with journal publication work. To discuss your study, send a short description and your target journal, if you have one, through WhatsApp or the contact page.
