Pre- and post-training VO2 at the VAT and VO2peak in patients randomized for prehabilitation. n = 24 for VO2 at the VAT, as 4 patients did not perform a post-training CPET. n = 16 for VO2peak, as 4 patients did not perform a post-training CPET and 8 patients did not perform a maximal effort on both CPETs. CPET indicates cardiopulmonary exercise test; VAT, ventilatory anaerobic threshold; VO2, oxygen uptake; VO2peak, oxygen uptake at peak exercise.
