Exercise capacity measures by intervention arm at baseline and follow-up

Variable				P value TET vs LAP, average effect across all follow-up visits
	Baseline	3 Mo	12 Mo
VO₂ peak(ml/kg/min)
TET	14.4	14.9 ± 0.6 (0.42)	16.5 ± 0.8 (0.01)	0.23
LAP	14.4	15.2 ± 0.6 (0.14)	14.3 ± 0.8 (0.87)	0.23
P value, TET vs LAP		0.65	0.06
Total Treadmill Time (s)
TET	335	416 ± 14 (0.09)	427 ± 20 (0.08)	0.73
LAP	335	411 ± 14 (0.21)	419 ± 21 (0.22)	0.73
P value, TET vs LAP		0.79	0.75

All values are estimated least squares means (± standard error of the mean) from repeated measures analysis of covariance adjusted for gender and baseline value. VO₂ peak is peak oxygen consumption. Baseline value is overall mean used to obtain least squares means at follow-up visits. P values for within group analysis comparing follow up visits to baseline values are reported adjacent to individual mean values.
