Variables associated with VO_2peak in the standardised regression model*

Variable	P value	Standardised coefficient
Body mass index	<0.001	−0.25
Physical activity summary index	<0.001	0.21
Patient global assessment	0.006	−0.14
Systolic blood pressure	0.016	−0.12
Resting heart rate	0.032	−0.11
Smoking	0.046	−0.10

*The model was adjusted for age and gender. The standardised coefficient gives the change of VO_2peak (mL/(kg x min)) for one SD increase in each variable.
