CAC prevalence in the CARDIA cohort (aged 32–47) stratified into low (GRS quintile 1), intermediate (GRS quintiles 2–4) and high (GRS quintile 5) genetic risk categories. High/Low indicates the ratio of the rate of CAC presence in the high genetic risk category to the rate of CAC presence in the low genetic risk category.

CAC = coronary artery calcium, GRS = genetic risk score
