Impact of Body Mass Index on Outcomes of Cervical Cerclage: A Systematic Review and Meta-Analysis.
Synthesis in Obesity facts, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe purpose of the review was to examine the impact of maternal body mass index (BMI) on outcomes of cervical cerclage for cervical insufficiency.
methodsThis prospectively registered review (CRD42024512436) searched PubMed, Embase, Scopus, and Web of Science for comparative studies published before 6 March 2024. Maternal and neonatal outcomes of females undergoing cerclage were compared based on BMI.
resultsSeven studies were included. Pooled data showed that the risk of preterm birth (PTB) (<37 weeks) was significantly increased in the obese vs. non-obese group (odds ratio 1.32, 95% confidence interval [CI]: 1.15, 1.51; I2 = 36%). Gestation age at delivery in weeks was also found to be significantly lower in the obese group (MD: -2.47, 95% CI: -4.83, -0.12; I2 = 96%). There was no significant difference in the risk of preterm premature rupture of membranes and chorioamnionitis between the two groups. Still, the rate of cesarean sections was significantly higher in the obese group. Neonatal birth weight in grams was not found to be significantly different between obese and non-obese groups but the risk of neonatal intensive care unit (NICU) admission was significantly increased in the obese group.
conclusionLow-quality evidence indicates that obesity may lead to an increased risk of PTB in women undergoing cervical cerclage. The risk of cesarean section and NICU admission is also increased in obese females.
