 A-D. Bland-Altman plots for the agreement between questionnaire-VO2peak and CPET-VO2peak at T0. The dashed lines represent the 95%-LoA, from − 1.96 SD to + 1.96 SD. The solid line represents ratio bias and the dotted line represents the zero bias line. A) FitMáx-VO2peak compared with CPET-VO2peak. B) FitMáx-VO2peak without cycling compared with CPET-VO2peak. C) VSAQ-VO2peak compared with CPET-VO2peak. D) DASI-VO2peak compared with CPET-VO2peak. Abbreviations: CPET, cardiopulmonary exercise test; DASI, duke activity status index; kg, kilograms; mL, milliliters; min, minute; VO2peak, peak oxygen uptake; VSAQ, veterans specific activity questionnaire</fig>
