In the 207 pairs of GDM cases and controls, the levels of Ln MASP-1 and Ln MASP-2 were also higher in women with GDM than in those women without GDM (means ± SD of Ln MASP-1 and MASP-2: 14.1 ± 0.54 vs. 14.0 ± 0.60, P = 0.009 and 13.2 ± 0.65 vs. 13.0 ± 0.62, P < 0.001, respectively) (Table 1). Here, MASP1 is linked to gestational diabetes.
