Besides that, apoM was also positively correlated with apoA-I in the T2DM with hyperlipidaemia group (r = 0.030, P <0.01), T2DM without hyperlipidaemia group (r = 0.347, P <0.001), and healthy controls (r = 0.338, P <0.001), although such association was not found in the hyperlipidaemia group (r = 0.123, P >0.05). Here, APOA1 is linked to type 2 diabetes mellitus.
