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
Objective: The objective of the study was to assess whether the measurement of the angle of progression in nulliparous women in labour can predict the mode of delivery. Methods: This prospective observational study was conducted at Benazir Bhutto Hospital, Rawalpindi Medical University from 16 Results: Seventy-eight patients were included in the study. Angle of progression was wider in patients who underwent vaginal delivery and narrower in patients who underwent cesarean section. AOP of 121 or more is associated with 86.6% of vaginal delivery and an angle of progression of 70 or less is associated with 83.3% of cesarean section. Conclusion: The angle of progression is a reliable tool for predicting the mode of delivery. Wider angle is associated with vaginal delivery and a narrower angle is associated with cesarean section.
