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
purposeTo develop a practical risk-stratification framework for unplanned cesarean delivery (CD) among term nulliparous individuals with hypertensive disorders of pregnancy (HDP) undergoing induction of labor (IOL).
methodsThis was a retrospective cohort study at a single tertiary care center (January 2010-March 2025) of nulliparous individuals with singleton gestations diagnosed with HDP undergoing IOL at ≥ 37 + 0 weeks. We excluded multiple gestations, major fetal anomalies, planned CD, or intrauterine fetal death. We included demographic and pregnancy characteristics available prior to induction and evaluated association with unplanned CD. Stepwise backward logistic regression was used to build a model for identifying independent predictors of unplanned CD. Sensitivity, specificity, and likelihood ratios (LR) were calculated.
resultsAmong 1,326 eligible individuals, 347 (26.2%) underwent unplanned CD. Independent predictors of CD were age > 35 years (adjusted odds ratio [aOR] 1.97, 95% CI 1.45-2.66), body mass index ≥ 30 kg/m
conclusionIn term nulliparous individuals with HDP undergoing induction, approximately one in four require CD. A simple model based on five routinely available pre-induction factors enables individualized counseling and shared decision-making at the bedside.
