BMI body mass index, HDL-cholesterol high-density lipoprotein-cholesterol, LDL-cholesterol low-density lipoprotein-cholesterol, SD standard deviation.

^aEach component of CKD diet score was added individually into the model (not adjusted for the other food components), adjusting for gender, age, BMI, caloric intake, smoking, alcohol consumption, school education, and physical activity. The variable serum triglyceride was log transformed due to skewed data. Bold P values indicate statistical significance.
