Abstract
From 2006 to 2024, I have carried out statistical reviews of about 700 manuscripts for Annals of the Rheumatic Diseases and RMD open. My most frequent review comments concern the following: 1. Report how missing data were handled. 2. Limit the number of covariates in regression analyses. 3. Do not use stepwise selection of covariates. 4. Validate prediction models. 5. Adjust for baseline values in randomised controlled trials. 6. Do not adjust for baseline values in observational studies. 7. Dichotomising a continuous variable can be a bad idea. 8. Student t test is better than nonparametric tests. 9. Mean (SD) are also relevant for nonnormally distributed data. 10. Adjusting P values for multiplicity. 11. Report estimate, CI, and (possibly) P value-in that order of importance. 12. Do not test for baseline imbalances in a randomised controlled trial. 13. Format for reporting CIs. 14. Mind the number of reported decimal places. 15. Report absolute numbers where relevant.
