χ2 test was used for comparison between observed and expected distribution. Kruskal-Wallis rank sum test stands for variance among 3 clusters:a, significant difference among the 3 groups. Significance is set at 0.05. Mann and Whitney test stands for comparison between 2 groups:b, significant difference between A and B;c, significant difference between A and C.d, significant difference between B and C. Significance is set at 0.01, after adjustment for multiple comparisons.HOMA-IR, Homeostasis Model Assessment of Insulin Resistance; SBP, systolic blood pressure; DBP, diastolic blood pressure; CRP, C reactive protein.
