Abstract

Objectives: To identify the best protocol for measurement of mean arterial pressure (MAP) in early pregnancy for the prediction of preeclampsia (PE). Methods: This was a prospective study in singleton pregnancies attending for a routine hospital visit at 11-13 weeks' gestation when a minimum of four recordings of MAP were taken from each arm. The performance of screening for PE by different combinations of MAP was compared to the protocol of the National Heart Foundation of Australia (NHFA). Results: The MAP was measured in 587 (2.4%) cases that developed PE and in 22,900 that were unaffected by hypertensive disorders in pregnancy. The area under the receiver operating characteristic curve (AUROC) for prediction of PE by MAP as recommended by the NHFA protocol was 0.773 (95% CI 0.768-0.778). This AUROC was not significantly different from the AUROC obtained by the average MAP of the first three measurements from one arm (0.765, 95% CI 0.760-0.771) or the average of the first (0.766, 95% CI 0.760-0.771), the first two (0.771, 95% CI 0.766-0.777), or the first three measurements from the two arms (0.773, 95% CI 0.768-0.778). Conclusion: Performance of screening for PE by taking the average of a minimum of two measurements from both arms is comparable to the NHFA protocol.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
