Nature Medicine initial submission: how much formatting is enough?

Preparing a first submission to *Nature Medicine* raises a practical question: how polished does the document need to look before an editor sees it?

The journal's current answer is intentionally flexible. An initial submission does not need special formatting, provided the study is presented clearly enough for editorial assessment and peer review. That flexibility can save time, but it is not the same as submitting an unfinished or difficult-to-navigate file.

This guide separates the journal's stated initial-formatting rules from a conservative preparation workflow. Always confirm the current Nature Medicine submission guidance before uploading.

Start with the journal's actual initial-formatting rule

For the initial submission, *Nature Medicine* does not require authors to rebuild a manuscript around an elaborate journal-specific visual template. The journal says the study should be described in a form suitable for editorial assessment and peer review.

That statement has two useful parts:

• You do not need to spend the first-submission stage perfecting publication typography.
• You do need to make the study understandable and reviewable.

The distinction matters. A manuscript can be visually simple while still being carefully prepared. Clear headings, stable figure numbering, readable tables, and an internally consistent reference list help an editor follow the work. Decorative formatting, custom page furniture, or attempts to imitate the final published article are unlikely to improve that first reading.

Treat the first-submission file as a review document, not a typeset proof.

Choose one of the accepted file formats

The journal currently accepts initial submissions in PDF, Microsoft Word, or TeX/LaTeX formats. Authors using TeX or LaTeX should provide a compiled PDF for this stage.

Choose the format that produces the most stable review copy:

• Use Word when that is the manuscript's real working source and the document opens cleanly without missing fonts, broken equations, or displaced figures.
• Use PDF when you need to preserve a stable visual layout across systems.
• Use TeX or LaTeX when that is the source environment, but compile it and inspect the resulting PDF before upload.

This is a practical choice, not a ranking of formats. The best initial file is the one that lets an editor and reviewers read the complete study without reconstructing the document.

Make the review path obvious

The journal's flexible first-submission policy leaves room for field-appropriate structure. Use that flexibility to reduce friction.

A reader should be able to locate the core parts of the study without guessing. Check that section headings describe the document's organization, that figures and tables appear in a sensible sequence, and that every in-text callout points to the intended display item. If supplementary material is part of the submission, label it consistently and make its relationship to the main manuscript clear.

These are practical reviewability checks rather than additional *Nature Medicine* formatting rules. They do not authorize a formatting tool to rewrite scientific content, create declarations, or decide how the study should be argued. Authors remain responsible for the research and its presentation.

Keep the manuscript visually restrained

Because special formatting is not required at initial submission, avoid spending time on styling that may disappear later.

A restrained file usually means:

• one readable body typeface rather than several competing fonts;
• consistent heading levels;
• predictable paragraph spacing;
• page breaks that do not strand a heading or separate a figure from its legend unnecessarily;
• equations and symbols that render correctly; and
• no tracked changes, unresolved comments, editing marks, or placeholder notes in the review copy.

None of these items is a substitute for the journal's current instructions. They are a conservative way to make a flexible-format manuscript easier to assess.

If a heavily styled template introduces broken numbering, awkward white space, or inconsistent captions, simplify it. Review clarity is more valuable than visual imitation of the published journal.

Check figures and tables as part of the manuscript

Even when the initial format is flexible, display items should still function as evidence inside the document.

Run a connected check across each figure or table:

1. The item is cited in the manuscript.
2. Its number matches the callout.
3. Its title or legend belongs to the correct item.
4. The content is legible at ordinary review size.
5. Any abbreviation, symbol, or panel label needed for interpretation is handled consistently.

Do not use formatting to repair or reinterpret research content. If a legend is scientifically incomplete, a panel label is ambiguous, or a table needs author judgment, return it to the responsible author rather than inventing a fix.

The goal of the formatting pass is to preserve the author's material in a coherent review package.

Compile TeX or LaTeX before upload

The most explicit file-specific instruction on the journal's initial-formatting page concerns TeX and LaTeX: submit a compiled PDF.

Do not treat successful source editing as proof that the review file is ready. Open the compiled PDF and inspect it from beginning to end. Look for missing references, unresolved citation markers, clipped equations, substituted fonts, blank pages, misplaced floats, and figures that no longer match their callouts.

Keep the source project organized even though the compiled PDF is the initial review document. If the manuscript advances, the journal notes that additional formatting of text and images will be required before publication. A clean source folder makes that later work safer.

Separate initial submission from later production formatting

The journal explicitly distinguishes the flexible initial submission from formatting required after acceptance. That boundary is useful for planning.

At the first-submission stage, focus on a clear and stable review copy. Do not assume that a flexible initial file is already production-ready. If the paper moves forward, text and image requirements may become more specific, and the current journal instructions should be checked again at that time.

This approach avoids two common errors:

• over-formatting a paper before the journal needs production-level files; and
• assuming that first-submission flexibility permanently removes later requirements.

Keep the editable source, original figures, and supporting files in a controlled folder so the team can respond without rebuilding the package from scattered versions.

Run a final review-copy check

Before opening the submission system, inspect the exact file that will be uploaded.

Confirm that:

• the chosen format is PDF, Word, or TeX/LaTeX with a compiled PDF;
• the complete study is present and readable;
• headings reveal the manuscript's structure;
• figures, tables, callouts, and legends agree;
• citations and references do not show unresolved markers;
• equations, symbols, and special characters render correctly;
• no comments, tracked changes, placeholder notes, or private editing instructions remain;
• the file name is clear and does not expose internal notes; and
• the document opens on a second device or in a second viewer without visible damage.

For a TeX or LaTeX manuscript, make the compiled PDF—not merely the source files—the focus of this final check.

Use flexibility to save time, not to skip preparation

*Nature Medicine* gives authors useful freedom at initial submission: no special journal template is required, and PDF, Word, and TeX/LaTeX are accepted. The practical standard is still a manuscript that an editor and reviewer can assess without fighting the file.

Articlo formats author-provided manuscripts and checks them against stored journal requirements. It does not write research, verify references, make submission decisions, or guarantee acceptance. Authors remain responsible for the scientific content and the journal's current instructions.
