Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Expectant Management | Expectant management (unless a medical indication arises) until at least 40 weeks 5 days. | 674 | 3,037 | OG000 | ClinicalTrials.gov |
| Group 2 | Elective Induction of Labor | Elective induction of labor between 39 weeks 0 days and 39 weeks 4 days~Elective Induction of Labor: Women randomized to induction of labor will undergo induction via oxytocin at 39 weeks 0 days to 39 weeks 4 days. Those with an unfavorable cervix (modified Bishop score \< 5) will first undergo cervical ripening (method left to the discretion of the patient's physician) in conjunction with or followed by oxytocin stimulation unless a contraindication arises. | 569 | 3,059 | OG001 | ClinicalTrials.gov |
