LGALS1 and gestational diabetes: Pooled analysis of the ten included studies [16,18,22,26,31,32,33,34,35,36] using the latest timepoint if multiple were available (Figure A2b), suggested no significant difference in late pregnancy hPL between women with GDM and controls (WMD = 0.47 μg/mL, 95% CI −0.14 to 1.09, p = 0.1), with moderate heterogeneity (I2 = 60%, p = 0.008).
