What's new — Irritable bowel syndrome¶
Generated 2026-09-03 from the publication dates of every paper cited in this condition's pages.
This page answers a different question from the curation log. The log says when we last edited a page; this says how recent the evidence on those pages is — so you can tell settled ground from a field that is actively moving, and jump straight to what has emerged lately.
How much of this condition's evidence is recent¶
| Published within | Cited papers |
|---|---|
| last week | 0 |
| last month | 1 |
| last 2 months | 5 |
| last 3 months | 9 |
| last 6 months | 16 |
| last year | 40 |
| older than a year | 326 |
Counts are cumulative: a paper from last week also counts inside "last month". Dates are PubMed publication or e-publication dates, so a paper may have appeared online before its journal issue.

Recency is not quality: an old paper may be the definitive one, and a new paper may not replicate. Use this to find movement, not to rank evidence. See open questions for what remains unresolved, and the curation log for when these pages were last revised.
