4a. What are the (un)favorable effects of routine cervical length screening (AD 20 weeks/gestational age 20 weeks) in low-risk pregnancy compared to no routine screening?

 

P: patients	pregnant women, low risk
I: intervention	cervical assessment: routine cervical length screening + intervention
C: control	no routine cervical length screening
O: outcome measure	preterm birth (<28, <34, <37 wk), (composite) outcome of neonatal morbidity and mortality (respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), proven neonatal sepsis, perinatal, and neonatal mortality).

P: patients	pregnant women with a history of excisional treatment, cervix uteral surgery, conization
I: intervention	cervical assessment: routine cervical length screening + intervention
C: control	no routine cervical length screening
O: outcome measure	preterm birth (<28, <34, <37 wk), (composite) outcome of neonatal morbidity and mortality (respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), proven neonatal sepsis, perinatal, and neonatal mortality).
