Furthermore, in age- and sex-adjusted analyses, it was observed that bilirubin interacted with low HDL cholesterol (interaction term: β = 0.440, P < 0.001), elevated triglycerides (interaction term: β = 0.289, P = 0.024), enlarged waist circumference (interaction term: β = 0212, P = 0.034), BMI (interaction term: β = 0.150, P = 0.048 and plasma insulin (interaction term: β = 0.190, P = 0.018), but not elevated glucose (interaction term: β = 0.091, P = 0.85) or high blood pressure (interaction term: β = −0.088, P = 0.45) on SAA (data not shown). Here, SAA1 is linked to hypertensive disorder.
