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; TP, total protein; Alb, albumin; GFR, glomerular filtration rate; isCGM, intermittent scanning continuous glucose monitoring (FreeStyle® Libre)
