Spearman correlation coefficients between change in exercise capacity following CPAP therapy and baseline patient characteristics.

	Change in V̇O2 max and peak vs Baseline BMI	Change in V̇O2 max and peak vs Age	Change in V̇O2 max and peak vs Baseline V̇O2 max and peak	Change in AT vs Baseline BMI
Spearman r	–.78	–.09	–.42	–.50
P-Value (two-tailed)	.02	.84	.29	.45

AT = anaerobic threshold, BMI = body mass index, V̇O₂ max = maximum volume of oxygen uptake, V̇O₂ peak = peak rate of oxygen uptake.
