A simple scoring tool using belly fat and good cholesterol levels before surgery can accurately predict how much belly fat will be lost after surgery, with 88% accuracy in new patient groups.

Scientific Claim

A predictive nomogram combining preoperative VAT and HDL-c levels demonstrated strong discriminatory power for VAT reduction after LSG, with an area under the curve (AUC) of 0.88 (95% CI 0.78-0.98) in external validation.

Original Statement

The ROC curve for the external validation group was also plotted (Fig. 2B), with the AUC value for the external validation of the prediction model being 0.88 (95% CI: 0.78–0.98).
