Of the original 1 500 women, 1 342 were suitable for this analysis (666 in the control group and 676 in the study group). The following were excluded: twins ( n= 17), prenatally detected fetal anomaly ( n= 9), early pregnancy loss ( n= 18), asymmetric fetal biometry on 1st US ( n= 5), later confirmed as not pregnant ( n= 13), and dating information not available ( n= 30) or insufficient ( n= 66). The mean age was 25.3 (SD ±5.4) years; the mean BMI was 26.2 (SD ±6.0) kg/m 2 ; and 23% of women were obese (Table 1). By best clinical estimate, 61.3% booked before 24 weeks. 9% were uncertain. The change in policy increased exposure to any US from 62.5% to 88.9% of women. Exposure to the 1st US at 24 weeks from 7.2% to 23.8% ( p <0.001).>
