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](https://www.bmj.com/lookup/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](http://www.strobe-statement.org/Checklist.html).
