  • C-statistics

Authors' conclusion

BP trajectories, based on early pregnancy BP measurements, improved ability to predict HDP diagnosis in diverse pregnant cohorts. BP trajectories may improve identification of high-risk patients for more intensive BP monitoring during pregnancy.

Study context

Population
Patients with a singleton delivery from 2012 to 2020 in a large urban academic center, excluding those with pre-existing hypertension or serious medical conditions
Participants
25,879 patients
Comparison
Inclusion of trajectories into predictive models compared to clinical risk factors alone
Outcome
HDP diagnosis, including preeclampsia and gestational hypertension
