LGALS3 and gestational diabetes: The subgroup analysis showed GDM patients had significantly higher plasma galectin-3 levels than the HP in the first and second trimesters (P < 0.05) in the normal weight group (pre-pregnancy BMI ≥ 18.5 and < 24.0 kg/m2), but no statistically significant differences were found in the pre-pregnancy BMI between GDM and HP groups.
