Values are presented as the original values × 100. , , . A “segments” variable is introduced into the mixed-effects model to account for arterial segments (bilateral CCAs, Bulbs, and ICAs for the carotid site; bilateral CFAs for the femoral site; and bilateral PLAs for the popliteal site). Interaction terms were retained in the final model if significant. ACR, albumin/creatinine ratio; AGEs, advanced glycation end-products; BP, blood pressure; Est CCr, estimated creatinine clearance rate; hs-CRP, high-sensitivity C-reactive protein.
