Post Hoc Sensitivity Analyses of the Primary Outcome

	Control group, % (n/N)	Telemonitoring group, % (n/N)	RR (95% CI)	P value
Original analysis of the primary outcomea	23.7 (137/578)	18.2 (87/477)	0.77 (0.62–0.98)	.03
Post hoc sensitivity analyses
1. Excluding patients in the telemonitoring group who did not access the telemonitoring device at least onceb	23.7 (137/578)	12.2 (51/419)	0.51 (0.38–0.69)	< .001
2. Assuming the rate of the primary outcome is the same as the cohort of study participants—21.2%c	23.3 (161/690)	19.1 (132/690)	0.82 (0.6–1.01)	.056
3. Assuming the rate of the primary outcome is the same as the control group—23.7%c	23.8 (164/690)	19.8 (137/690)	0.83 (0.68–1.02)	.08

Abbreviation: RR, relative risk

^aThe primary outcome was a composite of 30-day death or hospital readmission

^bExcluded 58 patients in telemonitoring group who did not access the telemonitoring device at least once; 36 of the 58 excluded patients had 30-day death or hospital readmission

^cTwo post hoc sensitivity analyses were used to evaluate the impact of missing outcomes on our results. In the first scenario, the missing composite outcomes were assigned the rate of the cohort of study participants. In the second scenario, the missing composite outcomes were assigned the rate of the control arm
