Receiver Operating Characteristic (ROC) curves and model prediction performance indicators for three anthropometric measures of obesity and 10-year CVD Risk. Receiver Operating Characteristic Curve for elevated BMI (blue), elevated waist-to-height ratio (green) and elevated waist-to-hip ratio (red) for 10-year CVD risk score greater than a 7.5%, b 10% and c 20%. AROC = area under the receiver operating curve); NRI = Net Reclassification Index; IDI = integrated Dissemination Improvement. Waist-to-hip ratio performs better across all performance indicators at all levels of 10-year CVD risk
