Odds ratios for carotid atherosclerosis by serum bilirubin quartiles within each gender.

CI, confidence interval. § Adjusted for confounding factors in model 1 of Table 4 by stepwise multiple logistic regression analysis. Subjects were divided into four groups based on quartile of serum bilirubin (men, Quartile-1, 0.13–0.54; Quartile-2, 0.55–0.73; Quartile-3, 0.74–1.02; Quartile-4, 1.03–2.00 mg/dL and women, Quartile-1, 0.21–0.51; Quartile-2, 0.52–0.67; Quartile-3, 0.68–0.88; Quartile-4, 0.89–2.00 mg/dL).Odds ratios for carotid atherosclerosis by serum bilirubin quartiles within each gender.
