Patients included in a clinical trial or patients who did not collect their medication personally were excluded. There were two different analyses: a comparative analysis of the persistence rates in three periods (weeks 1-48, weeks 48-96, and weeks 96-144); and a Kaplan-Meier analysis to evaluate the evolution of persistence.Results A total of 102 patients were included. Persistence rates were different in the three periods. They decreased during the course of the different periods, and the decline was more rapid between the first and second period. There were statistically significant differences in the non-persistence of the five drugs (p PB Bmj publishing group SN 2047-9956 YR 2016 FD 2016-09-01 LK http://hdl.handle.net/10668/19035 UL http://hdl.handle.net/10668/19035 LA en DS RISalud RD Apr 8, 2025
