¹Lower scores reflect lower fatigue;

²Lower scores reflect lower depression. VO_2peak: Peak oxygen uptake; Est. Treadmill VO_2peak: VO_2peak estimated via submaximal CPET; CPET: Cardiopulmonary exercise test; Est.: Estimated; RM: Repetition Maximum; SF-36: Short-Form-36; SCFS: Schwartz cancer fatigue scale; FACIT-F: Functional assessment of chronic illness therapy-fatigue; CES-D: Center for Epidemiologic Studies Depression Scale (short-form).
