Get your JCI Insight paper right the first time: a ready-made structure with the right abstract and citations, so editors see your science, not formatting slips.

Submitting to JCI Insight goes smoothly when your draft already matches the journal's own rules. Editors screen new manuscripts against the JCI Insight guide for authors before peer review, so formatting, structure, and required statements should be right on the first draft rather than repaired during upload. This template sets that structure up for you.
It is a manuscript shell aligned to JCI Insight. It covers front matter, the abstract the journal expects, a body organized to the journal's article types, and a reference list in the journal's required style. Confirm current scope and article types on the JCI Insight journal page before you draft.
Prepare the title, authors, affiliations, and ORCID iDs. Write the abstract to the journal's rule and word limit, organize the body to the article type, and apply the required reference style from the first citation. Complete every declaration (ethics, competing interests, funding, data availability) the JCI Insight guide for authors lists, and cite figures and tables in order.
The common failure modes are formatting or reference style that does not match the guide for authors, missing required statements, and an incomplete portal checklist. Clear all three against the JCI Insight guide for authors before you submit.
The shell mirrors what editorial staff check first: article-type fit, the abstract rules, required declarations, and the journal's reference style. For more detail see the author resources. When your draft is ready, upload it through the journal's submission system.
| Element | JCI Insight requirement |
|---|---|
| Abstract | Unstructured abstract of no more than 200 words stating the rationale, objectives, findings, and conclusions of the manuscript in a single paragraph without subheads. No primary data or references. Define all nonstandard abbreviations at first use. This applies to Research, Clinical Research and Public Health, Resource and Technical Advance, and Physician-Scientist Development manuscripts. Research Letter manuscripts do not have a separate abstract section |
| Main text | Research, Clinical Research and Public Health, and Resource and Technical Advance manuscripts: Recommended 9,000 words; maximum 12,000 words (all text inclusive of title page, full text, references, figure legends, and tables). Research Letter manuscripts: Maximum 1,200 words (all text including title page, main text, references, and figure legend or table, excluding Funding support section). Physician-Scientist Development manuscripts: Maximum 7,500 words (all text inclusive of title page, full text, references, figure legends, and tables) |
| Declarations | Ethics approval/consent as applicable; competing interests; funding; data availability |
| Figures/tables | Publication-ready; cited in order |
| Supplemental | Upload separately when used |
| Keywords | Keywords are requested during the online submission process, but no specific count, range, or format requirements (e.g., MeSH terms, editor-assigned) are stated in the author guidelines |
| References | Numbered citations in parentheses, cited sequentially in text. References formatted according to AMA Manual of Style (American Medical Association). When a publication has 3 or more authors, include only the first author followed by ', et al.' Journal names abbreviated per NLM Catalog–Journals database. No PubMed ID or extraneous information |
| Peer review | Single-blind (single-anonymous): reviewers know author identities, but reviewer identities are not disclosed to authors |
| Submission | accounts.jci.org/account_requests/new?continue=https%3A%2F%2Fwww.the-jci.org%2Fcontrollers%2FViewContextController.php |
Read the JCI Insight guide for authors once before drafting and once before upload. Draft the abstract after results are stable. Set the reference style before adding citations. Keep a cover letter that states your contribution and fit to JCI Insight in under a page.
Skim two or three recent JCI Insight papers to calibrate depth and figure style. Make the novelty clear in the first two pages. Deposit data and code when the policy on the JCI Insight journal page requires it. Disclose any preprint or conference version with identifiers in the cover letter.
Do one focused pass against the JCI Insight guide for authors: scope, length, reference style, required declarations, and figure quality. Then submit through the journal's submission system.
