Mid-trimester sonographic cervical consistency index to predict spontaneous preterm birth in a low-risk population
Objectives: To investigate the effectiveness of mid-trimester sonographic cervical consistency index (CCI) for the prediction of spontaneous preterm birth (sPTB) in low-risk pregnancies and to compare its performance with that of mid-trimester sonographic cervical-length (CL) measurement. Methods: This was a prospective cohort study of women with a singleton pregnancy examined by ultrasound at 19+
