ROC curves of <i>SS2</i> and <i>SS1 scores</i> for the prediction of sarcopenia one year after sleeve gastrectomy.

Abstract

The diagonal line represents the detection achieved by chance alone (AUROC = 0.50); the ideal AUROC is 1.00. The SS1 score takes into account SMA [skeletal muscle cross-sectional area at the third lumbar vertebrae (cm2)] and gender. The SS2 score takes into account SMI [skeletal muscle index: SMA/height2 (cm2/m2)] and gender.</p
