Similarly, the apoM levels in T2DM with hyperlipidaemia patients also showed no significant difference compared with patients of T2DM without hyperlipidaemia, whereas the HDL-C level was significantly lower in the former, suggesting that plasma apoM levels were also correlated with other factors, such as LDL-C, TC, and apoA-I, except for HDL-C [11, 18, 26]. This evidence concerns the gene APOA1 and type 2 diabetes mellitus.
