NYHA New York Heart Association

^aOdds ratios derived from non-linear mixed models, adjusted for study center; year at recruitment; study period; sex; baseline value of the endpoint variable, age, NYHA function classification, and 6-minute walk test

^bMeasured with the nine-item patient health depression scale (PHQ-9). PHQ-9 score was classified as <10 (no or mild depression) and ≥10 (moderate-to-severe depression) [14]. Odds ratios were calculated for PHQ-9 score ≥10 during follow-up, tested in the ordered logistic non-linear mixed model

^cMeasured with 36-item short-form questionnaire (SF-36) [13]. Odds ratios were calculated for a ≥2.5 point increase in physical component summary and mental component summary scores

^dOdds ratios were calculated for a 1-class decrease in NYHA functional classification

^eOdds ratios were calculated for a ≥50 m increase in 6-minute walking distance

^fAdherence was defined as the number of treatment days covered according to defined daily dose and measured at 6-month intervals. The categories for number of days covered were: 0, 1–90, 91–150, 151–196 and >196. Odds ratios were calculated for attaining a category for number of days covered during follow-up, tested in the ordered logistic non-linear mixed model
