  • Values are shown as mean and SD, unless indicated otherwise.

  • *Primary analysis adjusted for BL age, VO2max and sex.

  • †Multiple stochastic imputation of 100 dataset adjusted for the minimisation variables.

  • ‡Complementary analysis including patients attending ≥70% of supervised exercise sessions (n=33), adjusted for BL age, VO2max and sex.

  • VO2max, weight-corrected maximal oxygen uptake.
