The clinical characteristics of the study participants.

Note: Characteristics are reported as percentages for categorical variables and means (±SD) or medians (with interquartile range) for continuous variables. The study participants were divided into four groups based on eGFR quartiles ((≥102.35, 92.42–102.34, 83.67–92.41, and ≤83.66 mL/min/ 1.73 m2). Categorical variables are presented as counts and percentages. The values outside the parentheses are the number of subjects, and the prevalence is presented in parentheses. The first quartile of eGFR was used as the reference. * p<0.05 vs. Quartile 1. ** p<0.01 vs. Quartile 1. Abbreviations: eGFR, estimated glomerular filtration rate; BMI, body mass index; WC, waist circumference; BP, blood pressure; HDL, high-density lipoprotein; LDL, low-density lipoprotein.
