Association Between Nutritional Status and Severe Sarcopenia in Maintenance Hemodialysis Patients: A Multicenter Cross-Sectional Study with Diagnostic Model Development

Background

Sarcopenia is highly prevalent in maintenance hemodialysis (MHD) patients and is associated with adverse outcomes, yet simple bedside tools to identify those with severe sarcopenia remain scarce. We aimed to develop and internally validate a nomogram-based diagnostic model for severe sarcopenia using routine nutritional indicators.
