	n	Mean		95% Confidence interval
6MWD (m)
Baseline	43	451		418.6, 482.3
Post-intervention	43	471		437.8, 503.3
30 days postoperative	28	349		308.1, 390.7
Handgrip strength (kg)
Baseline	43	34		30.3, 36.9
Post-intervention	43	35		31.4, 38.1
30 days postoperative	29	31		27.0, 34.8

Data are presented as mean (standard deviation). Paired sample t test used for CPET variables (n=42) and sit-to-stand (n=27) variables and linear mixed models used for 6MWD (n=43) and handgrip strength (n=43). Abbreviations: 6MWD 6-min walk distance, CPET cardiopulmonary exercise test, AT anaerobic threshold, VO₂ peak volume of O₂ consumed at peak exercise, BSA body surface area
