Neutrophil-to-lymphocyte ratio as a novel predictor of sarcopenia in maintenance hemodialysis patients: a cross-sectional study exploring associations across body composition categories

NLR is independently associated with sarcopenia risk in hemodialysis patients, including those with obesity. These findings suggest NLR could serve as a simple, cost-effective tool for identifying hemodialysis patients at high risk of sarcopenia, potentially facilitating early intervention strategies.
