JCI Insight Formatting Requirements: Word Limits, Figures, References (2026)

JCI Insight's abstract requirements depend on article type. Original Research articles typically allow 200-word abstract limit, structured into sections (Background, Methods, Results, Conclusions) for clinical journals or unstructured for basic-science. The named editorial-culture quirk: jci insight reviewers expect both mechanistic depth and translational implications. Authors should confirm article-type expectations on the https://insight.jci.org/submit pages before drafting.

JCI Insight's policy emphasizes main-text completeness for translational research submissions. Figures should be high-resolution (300 DPI minimum for raster, vector formats preferred for line art), with all axes labeled and units noted. Supplementary materials supplement, not replace, main-text content. JCI Insight editors flag manuscripts that defer methodological detail or critical results figures to supplementary materials.

JCI Insight's reference style follows publisher-portfolio conventions, typically a numbered Vancouver-style format with abbreviated journal names. The reference list must be audited against Crossref + Retraction Watch. Recent retractions in the JCI Insight corpus include 10.1172/jci.insight.158147, 10.1172/jci.insight.149568, and 10.1172/jci.insight.165234; citing any of these without retraction-notice acknowledgment triggers a desk-screen flag.

Scope-fit framing missing from abstract. mechanism-only papers without translational-implication framing extend revision rounds. Check whether your abstract reads to JCI Insight's scope

Methods detail deferred to supplementary. Clinical observational studies without mechanistic underpinning extend reviewer consultation. Check if your methods package is reviewer-complete

Reference-list cleanliness. Recent retractions in the JCI Insight corpus we audit include 10.1172/jci.insight.158147 and 10.1172/jci.insight.149568. Check whether your reference list is clean

The JCI Insight formatting requirements are calibrated to translational research submissions. Authors who treat formatting as the last step (rather than incorporating it during drafting) face longer revision rounds. Manuscripts where formatting is checked before peer review save 1-2 weeks of editorial back-and-forth. The named editorial-culture quirk: JCI Insight reviewers expect both mechanistic depth and translational implications; mechanism-only or clinical-only papers extend revision. The recent retractions in the JCI Insight corpus affecting reference-style audit: 10.1172/jci.insight.158147, 10.1172/jci.insight.149568, 10.1172/jci.insight.165234.

In our pre-submission review work on JCI Insight-targeted manuscripts, three patterns consistently predict formatting desk-screen failure at JCI Insight (American Society for Clinical Investigation). The patterns below are the same ones Howard Rockman and outside reviewers flag at first-pass triage.

Scope-fit ambiguity in the abstract. JCI Insight editors move fastest on manuscripts whose contribution is obviously aligned with translational research. The named failure pattern: mechanism-only papers without translational-implication framing extend revision rounds. Check whether your abstract reads to JCI Insight's scope

Methods package incomplete for the journal's reviewer pool. JCI Insight reviewers expect specific methodological detail. Clinical observational studies without mechanistic underpinning extend reviewer consultation. Check if your methods package is reviewer-complete

Reference-list and clean-citation failure mode. Editorial team at JCI Insight (American Society for Clinical Investigation) screens reference lists for retracted-paper inclusion. Recent retractions in the JCI Insight corpus we audit include 10.1172/jci.insight.158147, 10.1172/jci.insight.149568, and 10.1172/jci.insight.165234. Citing any of these without a retraction-notice acknowledgment is an automatic desk-screen flag. Check whether your reference list is clean against Crossref + Retraction Watch

JCI Insight's author guidelines describe the rules. This guide describes the editorial culture behind the rules. Authors who read only the official guidelines often submit manuscripts that technically comply but fail at desk-screen because they miss the translational research editorial culture and the named failure pattern: mechanism-only papers without translational-implication framing extend revision rounds. The pre-submission reviews documented in our Manusights submission corpus surface these patterns explicitly. SciRev community surveys confirm the same patterns from the author-experience side. Together, the guidelines + editorial-culture lens + community signal create a more complete pre-submission picture than any single source.

The named editorial-culture quirk for JCI Insight is JCI Insight reviewers expect both mechanistic depth and translational implications; mechanism-only or clinical-only papers extend revision. Recent retractions in the JCI Insight corpus that authors should exclude from reference lists: 10.1172/jci.insight.158147, 10.1172/jci.insight.149568, 10.1172/jci.insight.165234.
