Meta-analysis results of all grade 3 to 5 adverse events in exercise compared to usual care presented as overall with subgroup analyses for 1) exercise mode, 2) supervision, 3) intervention length, 4) timing with respect to treatment, 5) cancer diagnosis, and 7) high quality studies only (n = 19 trials). Notes: Overall equals n = 21 because n = 2 studies involved multiple intervention arms; positive scores for risk difference indicate a lower risk of an adverse event with exercise compared to usual care
