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/m^{2}, No significant difference between area under the curve by women and men, and by age (p>0.05).
