Comparison of our cohort of brain tumor survivors with healthy controls and other chronic illness groups from Groen and colleagues²⁵

Fitness Variable	BTS	Healthy	CF	CHD
VO₂max (ml·kg⁻¹·min⁻¹)	31.8 (7.2)	49.3 (7.9)^***	42.5 (6.8)^***	33.7 (8.9)
HRmax (beats·min⁻¹)	187 (11)	193 (7)	188 (10)	164 (28)^***
RER	1.2 (0.1)	1.16 (.07)	1.19 (.06)	1.19 (.15)

VO₂max = peak oxygen uptake; HRmax = maximum heart rate; RER = respiratory exchange ratio; BTS= brain tumor survivors; CF=cystic fibrosis; CHD = chronic heart disease.

All values are mean (SD).

Single sample T-test comparisons with the BTS cohort:
