Strengthening the reporting of observational studies in epidemiology (STROBE) statement: guidelines for reporting observational studies

We fell victim to the perils of “copying and pasting” during the editing of this Analysis article by von Elm and colleagues (BMJ 2007;335:806-8, 20 Oct, doi: 10.1136/bmj.39335.541782.AD). In the table, the “recommendation” text intended for item 16 was overwritten by the text from item 13. The correct recommendation for item 16 (main results) is: (a) Give unadjusted estimates and, if applicable, confounder adjusted estimates and their precision (eg 95% confidence interval). Make clear which confounders were adjusted for and why they were included; (b) Report category boundaries when continuous variables were categorised; (c) If relevant, consider translating estimates of relative risk into absolute risk for a meaningful time period. The correct version of the table is available at www.strobe-statement.org/Checklist.html.
