Fig. 1From: Prescription characteristics associated with drug overdose risk among adults prescribed benzodiazepines: a cohort studyKaplan Meier Survival Curves of Overdose Events Among Incident and Continuing BZD Users by Age and BZD Exposures. MPR, medication possession ratio; BZD, benzodiazepine. For each panel, the y-axis presents the survival probability and x-axis is days from index BZD prescription. MPR log-rank (LR) test p-values: continuing cohorts < 65 (< .0001) and 65 + (< .0001). Average daily dose LR test p-values: incident cohorts < 65 (< .0001) and 65 + (< .0001); continuing cohorts < 65 (.03) and 65 + (< .0001). Days’ supply LR test p-values: incident cohorts < 65 (.02) and 65 + (< .0001); continuing cohorts < 65 (< .0001) and 65 + (< .0001)Back to article page
