Predictive model for preterm premature rupture of membranes following fetal endoscopy laser coagulation in twin-to-twin transfusion syndrome surgery.

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 develop a risk prediction model for preterm premature rupture of membranes (PPROM) after fetal endoscopy laser coagulation (FLC) for Twin-to-Twin Transfusion Syndrome (TTTS), identifying related influencing factors.
methodsA retrospective analysis was conducted on 414 parturients from six Chinese hospitals treated with FLC for TTTS between January 2016 and January 2025. Patients were divided into non-occurrence (n = 263) and occurrence groups (n = 151) based on PPROM during pregnancy. Logistic regression identified predictors, establishing the risk prediction model.
resultsUnivariate and multivariate logistic analyses revealed postoperative amniotic fluid leakage, operation time, and intraoperative amniotic fluid reduction rate as risk factors, while preoperative cervical canal length and Trocar insertion distance from the internal cervical OS were associated with reduced risk (all P < 0.05). ROC curve analysis showed an area under the curve of 0.802 (95% CI: 0.700-0.904), indicating good predictive efficacy. The goodness-of-fit test (P = 0.165 > 0.05) confirmed model fit, and calibration curves demonstrated acceptable accuracy. Clinical decision curves indicated net benefit.
conclusionThis model, incorporating postoperative amniotic fluid leakage, operation time, intraoperative amniotic fluid reduction rate, preoperative cervical canal length, and Trocar insertion distance, effectively predicts PPROM risk after FLC for TTTS. It can assess risks clinically and guide interventions to prolong pregnancy and improve outcomes.
