Women assigned to "Sweep" had their cervix swept by inserting the examining finger as high as possible past the internal cervical os, immediately followed by the placement of a 10mg Dinoprostone vaginal insert in the posterior fornix.
For women assigned to "No sweep": The only 10mg Dinoprostone vaginal insert were placed in the posterior fornix for cervical ripening

Vaginal delivery within 24 hours
Vaginal delivery within 24 hours is defined as vaginal delivery after 24 hours of initiating intervention (i.e. concurrent membrane sweeping with dinoprostone or only dinoprostone) on the first day of induction.
Time frame: Twenty-four hours of initiating intervention (i.e. membrane sweeping or PG) on the first day of induction
Cervical change in the bishop scores and cervical lengths
1. Cervical change based on the bishop score and cervical length induced by two cervical ripening methods(concurrent membrane sweeping with dinoprostone vs. dinoprostone) 2. Incidence of cesarean delivery 3. Successful labor induction (defined as an ability to achieve the active phase of labor corresponding to a cervical dilatation of \>=4cm). 4. The interval from start of oxytocin to delivery 5. Incidence of rupture of membranes 6. Incidences of vaginal bleeding and fever
Time frame: Initiation of oxytocin after removing dinoprostone vaginal insert
