hs-CRP, high sensitivity C-reactive protein; CIMT, carotid intima-media thickness.

aCarotid atherosclerosis was defined as the presence of carotid plaque or the increased mean CIMT value >0.9 mm at least one carotid artery.

P-values for categorical variables tested by chi-square and for continuous variable by t-test.
