Notes:

a Total sample number = 6 536 patients.

b No. refers to the number of prescriptions under each treatment regimen; % refers to the percentage of the total drugs prescribed under the four treatment regimens.

c 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.

d Pairwise group comparisons are performed taking primary care clinics as the reference.
