  1. HDL, high-density lipoprotein; LDL, low-density lipoprotein; eGFR, estimated glomerular filtration rate; HMW, high molecular weight. Data presented are mean ± standard deviation. Data for triglycerides, TG/HDL-C ratio, and serum adiponectin were skewed, and are presented as median (interquartile range). Data for triglycerides, TG/HDL-C ratio, and serum adiponectin were log-transformed for analysis. * Student's t-test or χ2 test.
