Correction to “Predictors of fatal and nonfatal overdose after prescription of opioids for chronic pain: a systematic review and meta-analysis of observational studies”

CMAJ has been made aware of an error that occurred in the Oct. 23, 2023, issue.1

In Figures 2, 3 and 4, the threshold at which risk increases or decreases should have been anchored at an adjusted odds ratio of 1, indicated by the grey vertical line, rather than the red vertical line, which indicates the pooled association.

This has been corrected at cmaj.ca.
