![]() ![]() There was no evidence of group differences for the outcomes of caesarean section, neonatal intensive care admissions or preterm birth less than 37 weeks. However, these results are based on a single trial, and we would recommend caution when interpreting this finding. Only one included trial assessed serious neonatal morbidity and found no evidence of group differences (RR 0.99, 95% CI 0.06 to 15.75 one study, 2016 participants).įor the comparison of a single Doppler assessment versus no Doppler, evidence for group differences in perinatal death was detected (RR 0.36, 95% CI 0.13 to 0.99 one study, 3891 participants). ![]() Results for perinatal death were as follows: (average risk ratio (RR) 0.80, 95% confidence interval (CI) 0.35 to 1.83 four studies, 11,183 participants). There were no group differences noted for the review's primary outcomes of perinatal death and neonatal morbidity. Overall, routine fetal and umbilical Doppler ultrasound examination in low‐risk or unselected populations did not result in increased antenatal, obstetric and neonatal interventions. Overall and apart from lack of blinding, the risk of bias for the included trials was considered to be low. All trials had adequate allocation concealment, but none had adequate blinding of participants, staff or outcome assessors. We included five trials that recruited 14,624 women, with data analysed for 14,185 women. ![]()
