Effectiveness of Targeted Cervical Length Screening Guided by a Preterm Birth Risk Scoring System in Reducing the Rate of Preterm Birth
China1,000 participantsStarted 2026-03
Plain-language summary
This cluster non-randomized controlled trial aims to evaluate the effectiveness and feasibility of a risk score-guided targeted cervical length screening strategy for the prevention of spontaneous preterm birth in routine community-based prenatal care. Pregnant women are first assessed using a simple preterm birth risk scoring system, and those identified as high risk undergo transvaginal cervical length screening followed by guideline-based preventive interventions when clinically indicated.
The primary objective of the study is to compare this targeted screening strategy with usual prenatal care in reducing the incidence of spontaneous preterm birth occurring between 28 and 36 completed weeks of gestation. Secondary objectives include evaluating the cervical length screening rate, adherence to cervical length screening recommendations, and selected maternal and neonatal outcomes.
Researchers will compare outcomes between women receiving risk score-guided targeted screening and those receiving routine prenatal care without use of the risk scoring system. All participants will be followed until delivery.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
