  1. Values are expressed as mean (± standard deviation) or median (interquartile range) (25–75%) (aStudent’s t test) or percentage (absolute number) (bχ2 test, with continuity correction when applicable). cNumber of subjects in sub-sample analyses. P-value of nonparametric variables was obtained after logarithmic transformation. Percentages of hs-CRP levels to categorical variables are shown in the rows. SBP systolic blood pressure, DBP diastolic blood pressure, HDL-c high-density lipoprotein cholesterol, LDL-c low-density lipoprotein cholesterol, HOMA-IR homeostatic model assessment.
