FIGURE 2 | Proportion of Days Covered (PDC) Density curves for (A) total cohort ( n = 289), (B) single-pharmacy users ( n = 195) and (C) multiple-pharmacy users ( n =94). Vertical lines are representative ofmean PDCfor each datasource. Thesedistribution plotsillustrate theconsistently larger PDCestimates calculated via claims records and the relative closeness in PDC estimates between the claim ’ s records and the combined claims records and pharmacy dispensing data.
