Figure 3. Unadjusted Incidence Rates for Risk-Enhancing Factors Across Coronary Artery Calcium Categories.

A, Combined risk-enhancing factors with low ABI excluded. B, Individual risk-enhancing factors. The dashed line represents the reference line (7.5%) above which statin therapy is recommended. ABI indicates ankle-brachial index; Apo B₁₀₀, apolipoprotein B₁₀₀; CAC, coronary artery calcium; CKD, chronic kidney disease; FamHx, family of history of premature atherosclerotic cardiovascular disease; hsCRP, high-sensitivity C-reactive protein; Lp(a), lipoprotein a; MetS, metabolic syndrome; PM, premature menopause; RENF, risk-enhancing factors; and TG, triglycerides.
