Levels of lipoprotein-associated apoC-III for quintiles of total plasma apoC-III. Figure shows median apoCIII-apoAI, apoCIII-apoB, and apoCIII-Lp(a) levels for quintiles of plasma total apoC-III. apoC-III, apolipoprotein C-III; apoCIII-apoAI, apoC-III content on apolipoprotein A-I containing lipoproteins; apoCIII-apoB, apoC-III content on apolipoprotein B-100 containing lipoproteins; apoCIII-Lp(a), apoC-III content on apolipoprotein(a).
