Figure 3. — Estimates and percentage of adherence to multidrug therapy according to 6 predefined measurements. The PDC_with≥1, PDC_wm, and DPPR measurements using the PxM (A) and FxM (B) approaches to defining the study’s end-date showed that a total of 2,739 (64.8%) and 2,506 (59.3%), 2,440 (57.7%) and 2,240 (53.0%), and 2,720 (64.4%) and 2,493 (59.0%) patients were adherent, respectively. The mean adherence across the 6 measurements varied from 72.7% to 79.8%.
