Opioid-specific risk of respiratory depression in non-cancer pain: a retrospective cohort study.
BMC medicine·July 8, 2026·PMID 42415029

These findings help clinicians select safer opioids and identify high-risk combinations, particularly in hospitalized patients where monitoring is intensive but events still occur.
