Receiving operating characteristic (ROC) curves discriminating between normotensive and prehypertensive people and cutoff points for cardiovascular risk indicators. All the indicators significantly discriminated between normotensive and prehypertensive men and women. The highest areas under the ROC curves were those of waist circumference, waist to height ratio, and lipid accumulation product for both, women (top left) and men (top right). The cutoff points, with their respective sensitivity and specificity, are displayed in the table at the bottom right. AIP = atherogenic index of plasma, BMI = body mass index, LAP = lipid accumulation product, VAI = visceral adiposity index, WC = waist circumference, WtHR = waist to height ratio.
