Cervical length at 23 weeks of gestation: relation to demographic characteristics and previous obstetric history

To examine the feasibility of introducing routine measurement of cervical length at 23 weeks of gestation, to establish the distribution of cervical lengths in a routine population of singleton pregnancies and to examine the relation between cervical length and demographic characteristics and previous obstetric history.
