ROC curve for the prediction of visceral fat >100 cm2 using an internal data set.
NVAI, new visceral adiposity index; VAI, visceral adiposity index; WC, waist circumference; BMI, body mass index; TG, triglyceride; HDL, high-density lipoprotein.

External validation of the NVAI using a validation set.
(A) Discrimination of the NVAI was good, with a predicted visceral fat of >100 cm2, and values of 0.879 (SE: 0.026, 95% CI: 0.828–0.931) for the NVAI. (B) Calibrated plots demonstrate a close approximation to the logistic calibration of each nomogram, indicating good agreement between predicted and observed outcomes when using the NVAI. Value of intercept was 0.098, Value of slope was 0.834. WC, waist circumference; MBP, mean blood pressure; TG, triglyceride; HDL, high-density lipoprotein; ROC, receiver operating characteristic.

ROC curve and AUC comparison of the NVAI for ASCVD risk and CVD.
(A) ROC curve for the prediction of the ASCVD risk using internal data set. (B) External validation for the prediction of the ASCVD risk using a subgroup of KNHANES IV-V. (C, D) ROC curve for predicting the presence of MI, angina, and stroke using the full data of KNHANES IV-V. Post-hoc analyses were conducted using the DeLong method. The cutoff value of the ASCVD 10-year risk score: ≥7.5%.
