Screening properties of %BF estimated by equation using BMI and WC to detect hypertension
AUC (95% CI) Cutoff Sensitivity(95% CI) Specificity (95% CI) PPV (95% CI) NPV (95% CI) LR+ (95% CI) LR- (CI 95%)
Women
%BF (equation with BMI) 0.73 (0.70- 0.76) 34.0 68.1% (62.3- 73.4) 68.2% (64.4- 71.8) 49.1% (44.1- 54.2) 82.6% (79.0- 85.7) 2.1 (1.9- 2.4) 0.5 (0.4- 0.6)
%BF (equation with WC) 0.73 (0.70- 0.76) 34.1 71.0% (65.4- 76.2) 65.8% (61.9- 69.5) 48.2% (43.3- 53.1) 83.5% (79.9- 86.7) 2.1 (1.9- 2.3) 0.4 (0.4- 0.5)
Men
%BF (equation with BMI) 0.70 (0.67- 0.73) 20.4 71.4% (66.6- 75.8) 59.8% (54.5- 65.0) 66.0% (61.2- 70.5) 65.7% (60.3- 70.9) 1.8 (1.6- 2.0) 0.5 (0.4- 0.6)
%BF (equation with WC) 0.69 (0.66- 0.73) 20.7 69.7% (64.8- 74.2) 63.4% (58.1- 68.4) 67.6% (62.8- 72.1) 65.6% (60.3- 70.6) 1.9 (1.7- 2.1) 0.5 (0.4- 0.6)

AUC: area under the curve, 95% CI: 95% confidence interval, PPV: positive predictive value, NPV: negative predictive value, LR+: positive likelihood ratio, LR-: negative likelihood ratio.

Note: The cutoff points units are: kg/m2, No significant difference between area under the curve by women and men, and by age (p>0.05).
