Uterocervical angle as a second trimester screening method for the prediction of preterm birth in a Filipino population in a tertiary government hospital

In the Philippines, universal screening in the second trimester for predicting preterm birth (PTB) has not been universally adopted and there is a lack of studies on screening locally. Recently, the uterocervical angle (UCA) has been introduced as another prediction tool for preterm labor hence it is important to validate its reliability and clinical utility.
