Performance of machine‐learning approach for prediction of pre‐eclampsia in a middle‐income country
Ultrasound in Obstetrics &Gynecology, Volume 63, Issue 3, Page 350-357, March 2024.ABSTRACT Objective Pre‐eclampsia (PE) is a serious complication of pregnancy associated with maternal and fetal morbidity and mortality. As current prediction models have limitations and may not be applicable in resource‐limited settings, we aimed to develop a machine‐learning (ML) algorithm that offers a potential solution for developing accurate and ...
