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
objectiveThis study investigates the role of anterior utero-cervical angle as a predictor of labor induction success, comparing outcomes between normal vaginal delivery and cesarean section groups.
methodsA prospective cohort study was conducted on 55 patients undergoing labor induction (46 normal vaginal delivery, 9 cesarean section). Parameters such as maternal age, weight, height, body mass index (BMI; calculated as weight in kilograms divided by the square of height in meters), cervical length, anterior cervical angle (ACA), Bishop score, and levator ani measurements were analyzed. Statistical significance was assessed using Fisher exact test, independent sample test, Mann-Whitney U test, or χ
resultsThe ACA was significantly different between normal vaginal delivery (108.02 ± 22.38°) and cesarean section (86.11 ± 26.09°) groups (P = 0.026). We determined an optimal ACA threshold of 96° for the prediction of failure of progression (sensitivity: 70%, specificity: 73%). Other significant differences included maternal weight (P = 0.0033), height (P = 0.0033), BMI (P = 0.0462), primiparity (P = 0.0161), and fetal gender (P = 0.0334). However, Bishop score, cervical length, and levator ani metrics showed no significant differences.
conclusionAlthough ACA differs significantly between vaginal delivery and cesarean section groups, its independent predictive value for induction success remains limited compared with factors like primiparity and BMI. Further prospective studies are needed to clarify its clinical utility.
