Fig. 3From: The ability of a submaximal cycle ergometer test to detect longitudinal changes in VO2maxBland Altman plots, including limits of agreement, for estimated and measured VO2max (L/min) at the baseline tests (left) and at the follow-up tests (right). Mean VO2max = (estimated + measured)/2. Black line: mean difference. Dashed line: ± 1.96 * SDBack to article page
