APOB and type 2 diabetes mellitus: The subsequent analysis of the association between the enzyme activities and lipoprotein subclasses revealed that (1) Lp-pLA2 was associated with small LDL-C, large IDL-C, and VLDL-C in the T2DM group but not in controls and (2) arylesterase was associated only with large/medium HDL-C in controls and only with some of the more proatherogenic ApoB lipoproteins in T2DM subjects.
