| Multivariate enter linear regression analysis was performed, including age (age), waist-to-height ratio (WHtR), waist-hip ratio (WHR), triglyceride (TG), total cholesterol (TC), the natural logarithm of the homeostasis model assessment of insulin resistance (ln HOMA-IR), fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), uric acid(UA), and 25-hydroxyvitamin D3 (25-(OH)D3) as independent variables, with skeletal muscle mass adjusted by weight (SMM/W) as the dependent variable. | ||||||||
