Forty-nine obstetricians from three European countries were asked when they would advise delivery for a preterm fetus failing to thrive in utero, given various gestational ages, and a range of either umbilical artery Doppler flow velocity waveforms or CTG variability measures. Their responses indicated a wide area of disagreement about the correct timing of delivery, and a willingness to randomise patients to clinical trials of management. The area of uncertainty corresponded to the gestational age and Doppler bands at which participants have been entered to the pilot phase of a randomised trial of timed delivery, the Growth Restriction Intervention Trial (GRIT).

Abstract
Forty-nine obstetricians from three European countries were asked when they would advise delivery for a preterm fetus failing to thrive in utero, given various gestational ages, and a range of either umbilical artery Doppler flow velocity waveforms or CTG variability measures. Their responses indicated a wide area of disagreement about the correct timing of delivery, and a willingness to randomise patients to clinical trials of management. The area of uncertainty corresponded to the gestational age and Doppler bands at which participants have been entered to the pilot phase of a randomised trial of timed delivery, the Growth Restriction Intervention Trial (GRIT).
