Univariate correlations of serum zinc concentration with measured variables in all subjects. Spearman’s rank correlation coefficients (r) and P-values are presented. BMI body mass index, HbA1c hemoglobin A1c, TC total cholesterol, LDL low-density lipoprotein, HDL high-density lipoprotein, TG triglyceride, GFR glomerular filtration rate, CKD chronic kidney disease, SMI, skeletal muscle index
Data are presented as number, mean ± S.D., or median (25th–75th percentiles)
