  1. Notes:
  2. a Total sample number = 6 536 patients.
  3. b No. refers to the number of prescriptions for each class of drug; % refers to the percentage of the total prescriptions for the six classes of drugs. As a result of missing data, the sum of the total number of prescriptions over the four types of clinical facilities is smaller than the overall number of prescriptions. The sum of the prescription rates for all six classes of drugs exceeds 100% because the average prescription contained more than one drug.
  4. c CCBs = calcium channel blockers; ACE = angiotensin-converting enzyme; ARBs = angiotensin receptor blockers.
  5. d Pairwise group comparisons are performed taking primary care clinics as the reference.
  6. # Significant p-value with the Bonferroni-adjusted α-level, p < 0.0017
