Secondary analysis: Continued use of devices for participants who were initially able to connect to the devices during the first month. The n (%) values are given with regard to baseline device connection.

Device	On-site (N=101)			Remote (N=93)			Difference in proportion of continued device use between study arms
	Baseline connection, n	Third month device use, n (% baseline)	Fifth month device use, n (% baseline)a	Baseline connection, n	Third month device use, n (% baseline)	Fifth month device use, n (% baseline)	Mean percentage difference between study arms in baseline connection rate (95% CI)	Mean percentage difference between study arms in fifth month device use rate (95% CI)
