Table 2.

Predictive accuracy of nonexercise estimated CRF classification of lowest cardiovascular fitness against the reference CRF.

Group	Low CRFa (lowest quintile)				Low CRF (lowest quartile)				Low CRF (lowest tertile)
	ACCb (%)	PPVc (%)	SENd (%)	ACC (%)		PPV (%)	SEN (%)	ACC (%)		PPV (%)	SEN (%)
Male participants	81.5	44.7	69.2	79.5		50.9	67.4	77.2		59.9	66.7
Female participants	80.6	43.9	57.8	77.9		55.4	55.6	74.9		60.4	66.9

^aCRF: cardiorespiratory fitness.

^bACC: accuracy.

^cPPV: positive predictive value.

^dSEN: sensitivity.
