Serum Estradiol/Testosterone ratio as a cost-effective biomarker for early prediction of pre-eclampsia in LMIC settings: A prospective cohort study
This prospective cohort study demonstrates that a first-trimester serum estradiol-to-testosterone ratio of ≤3.92 serves as a cost-effective, independent biomarker for predicting pre-eclampsia in low- and middle-income country settings, offering high sensitivity and a more than five-fold increased risk for affected women.
