Receiver operating curve cut-offs for cardiorespiratory fitness (CRF) to predict overweight/obesity for different anthropometric indices, stratified by sex.

Study variables	Body-mass index (kg/m2; ≥85th percentile denotes overweight/obesity)
VO2max (mlO2/kg/min)	AUC	95% CI	Std. error	Value of p	Cut-off point
Boys (N = 766)	0.83	0.78–0.88	0.027	<0.001	44.6
Girls (N = 866)	0.86	0.82–0.90	0.022	<0.001	41.0
	Waist circumference (cm; ≥85th percentile denotes overweight/obesity)
VO2max (mlO2/kg/min)	AUC	95% CI	Std. error	Value of p	Cut-off point
Boys (N = 766)	0.77	0.71–0.83	0.031	<0.001	46.4
Girls (N = 866)	0.83	0.79–0.88	0.024	<0.001	40.8
	Waist-to-height ratio (≥0.5 denotes overweight/obesity)
VO2max (mlO2/kg/min)	AUC	95% CI	Std. error	Value of p	Cut-off point
