Regarding the other apolipoproteins, the blood plasma level of ApoB was positively correlated with the concentration of LDL-C as observed in all the patients together (r = 0.47, p < 0.05, Figure 3A) as well as in the subjects without CAD and diabetes (NCAD(−), r = 0.84, p < 0.05, Figure 3B). This evidence concerns the gene APOB and diabetes mellitus.
