Clinical Characteristics Associated With Very Preterm Delivery Despite Transabdominal Cerclage: A Cohort Study.
Observational study in BJOG : an international journal of obstetrics and gynaecology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo identify factors associated with unsuccessful transabdominal cerclage (TAC) insertion, defined as delivery before 32 weeks, including maternal demographics, preterm birth risk factors, operative details (laparoscopic or open, pre-pregnancy or during pregnancy) and subsequent cervical length.
designObservational cohort study.
settingA tertiary-level London hospital. SAMPLE: Women who underwent TAC between 2011 and 2024 and consented to inclusion in the Preterm Clinical Network (PCN) Database.
methodsData were collected from the PCN database and maternity records.
main outcome measuresCharacteristics of women delivering before versus after 32 weeks were compared using student's t-test where data were continuous and chi-squared where data were categorical (SPSS version 29.0).
resultsAmong 125 pregnancies following TAC, eight (6.4%) delivered before 32 weeks. Previous trachelectomy was strongly associated with preterm delivery (p < 0.0001). Mean cervical length differed significantly between groups: first trimester (19.3 mm vs. 33.8 mm, p < 0.001) and second trimester (18.8 mm vs. 31.9 mm, p < 0.001). Of 30 women with prior pregnancies using the same TAC, 80% (24/30) achieved at least one term birth and 13.3% (4/30) had two or more term deliveries.
conclusionTAC is highly effective, with over 90% of women delivering beyond 32 weeks. Factors linked to unsuccessful TAC include prior trachelectomy and short cervical length in early pregnancy. Effectiveness persists across subsequent pregnancies, with many women achieving multiple term births using the same TAC.
