Comparison of fetal biometry and neonates' BW by gestational age between normal glucose-tolerant women (group A) and women diagnosed with GDM (group B and group C) at 24-28 weeks of gestation, based on the NHS risk stratification criteria.
| Biometric parameters (percentiles) | Group A Normal glucose-tolerant women (N = 550) |
Group B HR women with GDM (N = 67) |

Data are expressed as the mean ± SD. HR: high risk; MR: medium risk; LR: low risk; HC: head circumference; BPD: biparietal diameter; TCD: transcerebellar diameter; AC: abdominal circumference; FL: femur length; EFW: estimated fetal weight; BW: birth weight. Differences between groups are compared with the Mann-Whitney test. ‡P < 0.05 group A vs. group B; ∗P < 0.05 group A vs. group C; ∗∗P < 0.05 group B vs. group C.
