Abstract

KEY POINTS: Adverse muscle composition is common in CKD; affected individuals face a higher risk of premature death. Adverse muscle composition is an independent and strong predictor of all-cause mortality in CKD. Muscle health evaluation can identify patients at high risk and support targeted prevention strategies. BACKGROUND: Adverse muscle composition (AMC), defined by low muscle volume and in…
