This study evaluates the ability of two reviewers to detect independently an early diastolic notch in 1371 uterine artery Doppler velocity waveform recordings. Agreement between the two reviewers for the detection of uterine artery notching was assessed by using the Kappa statistic. The inter‐rater reliability for the detection of unilateral notching was 0.75 (95% CI 0.70–0.80), whereas that for the presence or absence of bilateral notching was 0.66 (95% CI 0.60–0.71). The results suggest that there was good reviewer agreement for the presence or absence of a notch on uterine artery Doppler velocimetry.
