Figure 1 (A–C) Classification and regression tree analysis for subgroups of adherent and persistent patients with fibromyalgia. (A) Medication possession ratio (MPR): total duloxetine supply days/365. Node size (N) >250. Partition testing: F-test, α = 0.05. (B) Adherence (low, high): adherence = high if MPR ≥ 0.80; adherence = low if MPR < 0.80. Node size (N) >250. Split testing: Pearson χ2, α = 0.05. (C) Duration of therapy (Dur): duration of therapy from the index date to the earliest of either the ending date of the last prescription, the date of the first gap of >15 days between prescriptions, or the end of the study period (12 months). Node size (N) >250. Partition testing: F-test, α = 0.05.
