Association between positive aPL based on either manufacturer’s threshold (A) or at least 40 units threshold (B) and future ASCVD events were assessed in Cox proportional hazard models adjusted for known cardiovascular risks including age, ethnicity, smoking history, hypertension, diabetes, and lipid profiles. aCL indicates anticardiolipin; aPL, antiphospholipid antibodies; aPS/PT, antiphosphatidylserine/prothrombin; aβ2GPI, anti–beta-2 glycoprotein I; HR, hazard ratio; NA, not applicable (HR not calculable due to 0 events in aPL group).
