When the subjects with T1DM were dichotomized in two separate groups by median CEC capacity, the low CEC group was different when compared to high CEC group in terms of having lower total HDL cholesterol, lower large HDLp and lower HDL-z, lower Apolipoprotein A, lower ratio of Apolipoprotein A/Apolipoprotein B and higher total LDLp and small LDLp (Table 2). This evidence concerns the gene APOB and type 1 diabetes mellitus.
