Clinical Events As a Function of Adherence in the AT Group (post hoc analysis)

Event	UC		< 90 minutes/week		≥ 90 minutes/week
	No.	%	No.	%	No.	%
All-cause mortality and all-cause hospitalization	27	67	17	84	16	66
Cardiovascular mortality and cardiovascular hospitalization	16	41	16	83	13	54
Cardiovascular mortality and HF hospitalization	8	20	10	52	4	16
All-cause mortality, all-cause hospitalization, emergency department visit, or urgent clinic visit for HF exacerbation	35	95	18	100	19	91
All-cause mortality	4	11	4	19	1	4
Cardiovascular-related mortality	1	3	2	11	1	4

NOTE. Sample size for the usual care (UC) group: n = 43; for the aerobic training (AT) group: < 90 minutes/week, n = 22; ≥ 90 minutes/week, n = 25. Cumulative event rates were calculated by using the Kaplan-Meier method and were reported at 2 years of follow-up. The Cox proportional hazards regression model was used to compare groups by using all available follow-up data. Data are No. of clinical events and Kaplan-Meier estimates at 2 years (%).
