Table 4 Comparisons of cardiorespiratory fitness and physical function between children with cancer and healthy age-and sex-matched children at baseline (median of 12 days in the intervention group and 27 days in the control group)

From: Effects of a physical activity program from diagnosis on cardiorespiratory fitness in children with cancer: a national non-randomized controlled trial

  1. VO2peak, sit-to-stand, timed-up-and-go, and handgrip strength are reported in mean and standard deviation. The p values represent a comparison between a patient group (the intervention group and the control group) and a group of healthy children (the subgroup of ambassadors or historic healthy age- and sex-matched children)
