MASP2 and gestational diabetes: Low MASP-2 (i.e., <13.4 relative units) and high DCA (i.e., >0.28 nmol/mL) used as the reference, the copresence of high MASP-2 and low DCA (i.e., ≤0.28 nmol/mL) enhanced the ORs of high MASP-2 alone and low DCA alone, respectively, from 2.53 (95% CI: 1.10–5.85) and 2.24 (1.21–4.17) up to 10.6 (4.22–26.4) for GDM.
