The shown within-group differences are estimates extracted from the linear mixed-effects models. In group A, exercise intervention was initiated during chemotherapy; in group B, exercise intervention was initiated after chemotherapy.

^a1 baseline measurement of peak oxygen uptake had to be stopped early because the patient did not tolerate the mouthpiece. This patient was considered a dropout at time 0.

^b1 baseline measurement was not measured correctly because of technical difficulties.
