All baseline and 3–month values are unadjusted means ± SDs; all within-group changes are unadjusted mean (95% CI) and expressed as absolute change from baseline. Mean net differences were calculated by subtracting the within–group changes from baseline in the control group from the within–group change from baseline in the allo-HCT group after 3 months. *p < 0.05, ***p < 0.001 vs. baseline. VO2peak, peak oxygen uptake; HRpeak, peak heart rate; RER, respiratory exchange ratio; peak a–vO2diff, peak arteriovenous oxygen difference.
