aRR, adjusted risk ratio; CI, confidence interval.

*Adjusted for age and sex with direct standardization; the 2013 total Dutch population cohort was selected as a reference.

Opioid poisoning cases were derived from hospitalization and death dataset for the year in concern, and duplicate cases were filtered out. ICD-10CM codes used to identify opioid poisoning are reported in the Supplement online. Opioid prescriptions were identified by ATC code N02A.
