Abdominal circumference velocity 11.23 ± 1.00(8.19–14.28) 10.72 ± 1.00(7.70–14.00) <.0001
Head circumference velocity 10.68 ± 0.77 (8.54–13.51) 10.50 ± 0.80 (6.79–12.67) 0.001
Biparietal diameter velocity 3.08 ± 0.27(2.31–3.99) 3.01 ± 0.28(1.96–3.85) <.0001
Femur length velocity 2.50 ± 0.22(1.89–3.01) 2.47 ± 0.21(1.54–3.08) 0.014
