Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Gestational Age-Specific Cervical Length | Between 28 weeks 0 days and 33 weeks 6 days of gestation. | Cervical length will be measured in millimeters via transvaginal ultrasound and analyzed according to gestational age in completed weeks and days at the time of measurement. The shortest of at least three technically acceptable measurements will be recorded. |
| Secondary | Gestational-Age Category at Cervical-Length Assessment | At each cervical-length assessment from 28 weeks 0 days through 33 weeks 6 days of gestation; up to three assessments per participant. | Gestational-age category at each cervical-length assessment: 28 weeks 0 days to 29 weeks 6 days; 30 weeks 0 days to 31 weeks 6 days; or 32 weeks 0 days to 33 weeks 6 days. |
| Secondary | Short Cervix During the Third Trimester | Between 28 weeks 0 days and 33 weeks 6 days of gestation. | A short cervix will be defined as a cervical length of 25 mm or less, measured via transvaginal ultrasound. |
| Secondary | Gestational Age at Delivery | At delivery. | The gestational age at delivery will be recorded in completed weeks and days, determined using a study-defined pregnancy dating method based on the first-trimester or early second-trimester ultrasound. |
| Secondary | Number of Participants With Preterm Birth Before 37 Weeks of Gestation | At delivery. | Preterm birth is defined as delivery occurring before 37 weeks 0 days of gestation, irrespective of whether it follows spontaneous labor, preterm prelabor rupture of membranes, or a medical indication. |
| Secondary | Number of Participants With Medically Indicated Preterm Delivery Before 37 Weeks | At delivery. | Medically indicated preterm delivery is defined as induction of labor or prelabor cesarean delivery before 37 weeks 0 days due to documented maternal or fetal medical reasons. Record the primary indication when available. |
| Secondary | Number of Participants With Spontaneous Preterm Birth Before 37 Weeks | At delivery. | Spontaneous preterm birth is defined as delivery before 37 weeks 0 days following spontaneous labor onset or preterm prelabor rupture of membranes, without resulting from a planned induction or prelabor cesarean delivery for maternal or fetal medical reasons. |
| Secondary | Number of Participants With Early Preterm Birth Before 34 Weeks | At delivery. | Early preterm birth is defined as birth before 34 weeks 0 days of gestation. |
| Secondary | Number of Participants With Late Preterm Birth | At delivery. | Late preterm birth is defined as birth from 34 weeks 0 days through 36 weeks 6 days of gestation. |
| Secondary | Number of Participants With Term Birth | At delivery. | Term birth is defined as birth at or after 37 weeks 0 days of gestation. |
