Figure 3 Prevalence of CAD among subgroups with variation in inflammation and CMV infection. When adjustment for CAD risk factors, the odds ratios for CAD were 1.3 (95% CI, 0.4 to 4.4; p = 0.7) in the subgroup with CMV seropositivity alone, 2.3 (95% CI, 0.7 to 7.5; p = 0.2) in the subgroup with elevated CRP levels alone, and 4.3 (95% CI, 1.4 to 13.1; p = 0.01) in the subgroup with combined CMV seropositivity and elevated CRP levels. Overall liner trend achieves significance even after adjustment for CAD risk factors (p = 0.0016). CMV Ab+ or CMV Ab–: CMV antibody response positive or negative, respectively; CRP >0.5+ or CRP >0.5–: CRP levels >0.5 mg/dl or CRP levels  0.5 mg/dl, respectively.
