Fig. 1: Hazard ratios among patients with type 2 diabetes mellitus, comparing 2 subgroups within each drug-monotherapy group: 1A, hazard ratios for deaths from all causes, according to median split for drug exposure (i.e., whether their individual daily dose was more than the group median [higher subgroup] or less [lower subgroup used as the reference]); 1B, for deaths attributable to an acute ischemic event, also according to median split for drug exposure; and 1C, for all-cause mortality, according to drug-treatment adherence (patients were assigned to the poor-adherence [reference] subgroup if their adherence rate was < 0.8 or if they stopped therapy > 6 months before end of follow-up). Error bars indicate 95% confidence intervals. *Either chlorpropamide or tolbutamide.
