  1. HDL High-density lipoprotein, LDL Low-density lipoprotein, GFR Glomerular filtration ratio. Data presented are mean ± standard deviation. Data for triglycerides and HemoglobinA1c is skewed, and presented as median (interquartile range) values. * P-value: Student’s t-test for the continuous variables or the χ2 -test for the categorical variables. Bold values indicate significance (p < 0.05)
