Cut-off of body mass index and waist circumference to predict hypertension in Indian adults

Figure 1 Criterion values and coordinates of the receiver operating characteristic curve. A: Receiver operating characteristic (ROC) analysis for body mass index (BMI) as a predictor of hypertension among men revealed area under the curve = 0.714. The optimal cut-off for maximum sensitivity and specificity was 24.5; B: ROC analysis for BMI as a predictor of hypertension among women revealed area under the curve = 0.821. The optimal cut-off for maximum sensitivity and specificity was 24.9; C: ROC analysis for waist circumference as a predictor of hypertension among men revealed area under the curve = 0.784. The optimal cut-off for maximum sensitivity and specificity was 83; D: ROC analysis for waist circumference as a predictor of hypertension among women revealed area under the curve = 0.815. The optimal cut-off for maximum sensitivity and specificity was 78.
