Comparison of Change in Cardiopulmonary Exercise Testing Parameters in Upper Tertile vs Lower Tertiles of MIP Change

Parameter Upper Tertile of MIP Change, Mean±SD Lower Tertiles of MIP Change, Mean±SD P Value
Change in workload, W 1.2±8.2 −0.7±11.8 0.71
Change in peak VO2, L/min −0.5±−1.7 −1.9±3.6 0.26
Change in VT, L 139.0±156.5 −106.3±305.9 0.50
Change in VE/VCO2 0.1±2.4 −3.6±5.0 0.16

MIP indicates maximal inspiratory pressure; VCO2, carbon dioxide production; VE, minute ventilation; VO2, oxygen consumption; VT, tidal volume.
