  1. CKD, chronic kidney diseases; HDL, high density lipoprotein; HOMA-IR, homeostatic model assessment of insulin resistance; hs-CRP, high sensitivity c-reactive protein; MUFA, mono-unsaturated fatty acid; PUFA, polyunsaturated fatty acid; values are expressed as a mean and standard error of the mean; Q1-Q4; quarters. Quarters were derived based on the distribution of each targeted food pattern generating four groups with approximately equal number of participants.
