Association between the ratio of uric acid to high-density lipoprotein cholesterol (UHR) and the abnormal risk of sarcopenia: Evidence from two large population-based surveys and interpretable machine learning-driven sarcopenia screening
Background Sarcopenia is a geriatric syndrome linked to nutritional intake, chronic inflammation and metabolic dysregulation. While uric acid (UA) and high-density lipoprotein cholesterol (HDL-C) are recognized biomarkers, their specific relationship with sarcopenia remains debated. The uric acid-to-HDL-C ratio (UHR) h...
