How to Convert Your MD/MS Thesis into a Journal Article

Your thesis took two years of recruitment, analysis and writing. Turning it into a journal article lets other clinicians actually use your findings, and publications may matter for your career and for regulatory or institutional requirements. Yet many theses never become papers, because the resident tries to submit a shortened thesis instead of writing an article.

A thesis shows examiners that you can do research. A paper tells busy readers one clear finding in a few thousand words. This guide covers how to choose that finding, cut the thesis into IMRaD format, settle authorship fairly, pick a genuine journal, follow reporting guidelines, write the cover letter and respond to reviewers.

1Start with One Main Message

Before you open the thesis file, write one sentence that states the most important finding. For example: “In adults with [condition] at a tertiary hospital, [marker] above [cut-off] was associated with [outcome].” That sentence decides what stays in the paper and what goes.

• Pick the primary objective. The main paper should usually answer your primary objective. Secondary objectives can be summarised briefly or, if substantial and genuinely distinct, developed later.
• Do not split one study into many small papers just to increase the count. Journals discourage this kind of “salami slicing”, and editors may reject overlapping submissions.
• Be honest about negative results. A well-conducted study with a non-significant primary result can still be publishable, especially if it is adequately described and the limitations are clear.

2The IMRaD Cut-Down: Thesis to Paper

Most original articles follow the IMRaD structure: Introduction, Methods, Results and Discussion. Here is how thesis chapters map onto it.

Write the Methods and Results first, then the Discussion, then the Introduction, and finally the abstract and title. The abstract should be written last because it summarises the finished paper.

3Word Limits and What to Cut

Every journal sets its own limits in its instructions for authors – for the abstract, the main text, the number of tables and figures, and the number of references. Original articles are typically limited to a few thousand words, and short reports or brief communications to much less. Read the instructions for authors of your target journal before you start cutting, and follow them exactly.

Practical ways to reduce length:

• Remove background explanation that any specialist reader already knows.
• Do not repeat numbers from tables in the text; describe the key findings only.
• Merge small tables, and convert one table into a figure only if it makes the point clearer.
• Cite a published protocol or standard method instead of describing it in full.
• Cut the reference list to what is needed, and reformat it to the journal’s style. Our Vancouver referencing guide covers the style many medical journals use.

4Authorship: ICMJE Criteria

Many medical journals follow the ICMJE Recommendations, which state that an author should meet all four of these criteria:

1. Substantial contributions to the conception or design of the work, or the acquisition, analysis or interpretation of data.
2. Drafting the work or revising it critically for important intellectual content.
3. Final approval of the version to be published.
4. Agreement to be accountable for all aspects of the work, ensuring that questions about accuracy or integrity are appropriately investigated and resolved.

In a thesis-based paper, the resident who did the work is usually the first author, and the guide is commonly the corresponding or senior author. Co-guides and colleagues who contributed to design, laboratory work or analysis may also qualify – but only if they meet all four criteria. Those who do not, such as someone who only referred patients or provided departmental support, can be thanked in the Acknowledgements.

Discuss authorship order with your guide before you start writing, not after the paper is accepted. It avoids awkward disputes later.

5Choosing a Journal and Avoiding Predatory Ones

Match the journal to the paper

• Scope: read the aims and scope and look at recent articles. Is your topic and study design something they publish?
• Indexing: check the journal’s claims yourself in the databases – PubMed/MEDLINE (via the NLM Catalog), Scopus, Web of Science, or DOAJ for open-access journals. If your publication is meant to count towards a requirement, check which indexing your university or regulator currently accepts.
• Costs: many open-access journals charge an article processing charge. Find the amount on the journal’s website before submitting.
• Article type: if your sample is small or the study is preliminary, a short communication may be more realistic than a full original article.

Warning signs of a predatory journal

• Unsolicited emails inviting you to submit, often flattering and with poor grammar.
• Promises of acceptance or publication within days.
• Indexing claims that cannot be verified in the actual database, or vague claims such as “indexed in Google Scholar”.
• No clear peer review process, editorial board members who cannot be verified, or a title that closely imitates a well-known journal.
• Fees that are unclear or revealed only after acceptance.

The “Think. Check. Submit.” checklist is a useful starting point for evaluating a journal. When in doubt, ask your guide or the institutional library before you send anything.

6Reporting Guidelines: STROBE, CONSORT, STARD

Reporting guidelines are checklists of what a paper must describe so that readers can judge it. Many journals ask you to upload the completed checklist with the manuscript. You can find them on the EQUATOR Network website.

Go through the checklist item by item against your draft. Gaps are common – for example, missing details on how participants were selected, how missing data were handled, or a flow diagram of screened and enrolled patients.

For trials, many journals that follow ICMJE require that the trial was registered in a public registry such as CTRI before the first participant was enrolled. If your thesis trial was not registered prospectively, check the journal’s policy before submitting. Also state your IEC approval and consent process clearly; our post on ethical standards in medical research covers the essentials.

7Writing the Cover Letter

Keep it to one page. A simple structure:

1. Address the editor by name if the journal lists one, and give the manuscript title and article type.
2. In two or three sentences, state the main finding and why it suits this journal’s readers.
3. Confirm that the manuscript is original, is not under consideration elsewhere, and that all authors have approved it.
4. Mention that the work is based on the first author’s MD/MS thesis at [institution], if applicable.
5. Declare conflicts of interest, funding, ethics approval and trial registration if relevant.
6. Give the corresponding author’s contact details.

8Handling Peer Review

Very few papers are accepted without changes. A request for revision is normal and is a good sign – the journal is interested.

• Read the comments, then wait a day before replying. Initial frustration fades.
• Respond point by point in a separate document: copy each comment, write your response, and state exactly where the manuscript was changed.
• Be polite even when you disagree. If a request is not possible – for example, additional data you did not collect – explain why and add it as a limitation.
• Do not add analyses that were never planned without making clear they are exploratory.
• If rejected, use the reviewers’ comments to improve the paper, reformat it for the next journal, and submit again. Do not submit to two journals at the same time.

9Getting Help with Publication

Converting a thesis into a paper is a different skill from writing the thesis itself.
