A series of studies have shown that an apoB-100/apoA-I ratio ≥ 0.9 was a fair predictor of presence of the metabolic syndrome (MetS) [60], and men with an apoB-100/apoA-I ratio >0.9 had also a faster growth of carotid artery intima-media thickness (IMT) than those below this value [61]. Here, APOA1 is linked to metabolic syndrome.
