APOA1 and type 2 diabetes mellitus: No statistical difference was observed in plasma apoM concentrations between the T2DM with hyperlipidaemia group (19.83 ± 7.41 ng/μL) and T2DM without hyperlipidaemia group (18.54 ± 10.33 ng/μL, P >0.05, Fig. 1d) similar to apoA-I (1.29 ± 0.33 g/L vs. 1.28 ± 0.31 g/L, P >0.05, Table 1).
