PON1 and type 2 diabetes mellitus: The quantification of lipoprotein subfraction distribution was carried out on a subsample, Lipoprint, including 202 controls and 90 T2DM subjects, in order to (1) identify additional potential confounders of the association between arylesterase activity and T2DM and (2) explore the effect of T2DM on the distribution of PON1 activities and Lp-PLA2 on lipoprotein subclasses.
