Efficacy of transabdominal cerclage by open laparotomy relative to existing risk factors.

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
introductionTo prevent extreme preterm birth, women with cervical insufficiency are eligible for transabdominal cerclage in case of prior failure or technical impossibility for transvaginal cerclage. This study aimed to identify patient characteristics that affect the success rate of transabdominal cerclage to prevent extreme preterm birth in women with cervical insufficiency. MATERIAL AND
methodsSingle-center retrospective cohort study in 87 women who underwent transabdominal cerclage by open laparotomy during first and early second trimester of pregnancy over a 20-year period. Participants were divided into subgroups according to indication for the intervention. Linear regression and meta-regression-analyses were performed to assess the effect of mean cervical length (before and after transabdominal cerclage placement) and gestational age of previous preterm birth, on gestational age at delivery. Kaplan-Meier analysis was performed to evaluate treatment effects on gestational age at delivery.
resultsOf 87 women, 62 women underwent a history-indicated and 25 an ultrasound-indicated transabdominal cerclage. Fetal survival was 92%: 91% in the history-indicated and 96% in the ultrasound-indicated group. Median gestational age at delivery was 37.3 weeks, with a median pregnancy prolongation of 163.0 days and with 92% of deliveries ≥34 weeks. Between groups, irrespective of singleton and twin pregnancies, outcomes were comparable. Gestational age at delivery was neither affected by cervical length before transabdominal cerclage, distance between transabdominal cerclage and external os, gestational age of previous preterm birth nor additional progesterone treatment.
conclusionsThe efficacy of transvaginal cerclage placement via open laparotomy during high-risk pregnancy is favorable and relates to fetal survival of 92%. Regardless of indication, pregnancy outcomes after transabdominal cerclage are similar, and independent of gestational age at previous preterm birth, cervical length before transabdominal cerclage placement, distance between transabdominal cerclage and external os, and additional progesterone administration.
