  1. 1. Abbreviations: HbA1C, glycated hemoglobin; HDL, high-density lipoprotein; BP, blood pressure; CRP, C-reactive protein; GFR, glomerular filtration rate; CKD, chronic kidney disease.
  2. 2. The t test was used for the difference in the means of two groups. The means of more than two groups were compared using one-way ANOVA followed by Scheffe’s multiple comparisons test. a-a, b-b, c-c indicates significant difference between two groups. Data are means ± SD. Significant difference (p < 0.05).
