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
Background Primary postpartum hemorrhage (PPH) remains a significant challenge in obstetric practice, contributing to maternal morbidity and mortality worldwide. Characterized by excessive bleeding within the first 24 hours following childbirth, PPH is a leading cause of maternal death. Uterine atony, inadequate contraction of the uterine muscle, accounts for the majority of PPH cases, particularly following lower segment cesarean section (LSCS). Bilateral uterine artery ligation (BUAL) and B-Lynch sutures have emerged as surgical interventions for managing PPH secondary to uterine atony during LSCS. Despite their demonstrated efficacy, comparative studies are needed to determine the optimal approach. Methods This prospective, comparative study was conducted among women experiencing primary postpartum hemorrhage (PPH) due to uterine atony following lower segment cesarean section (LSCS) over two years at a tertiary care hospital in India. A total sample size of 86 participants (43 per group) was determined using a convenient sampling technique within the defined study period. Participants were randomized into two groups: the BUAL group and the B-Lynch suture group. The primary outcome was intraoperative blood loss (ml). Statistical analysis was conducted using IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp., with significance set at p < 0.05. Results The mean age of study participants was 28.6 years (± 4.2) in the BUAL group and 29.1 years (± 4.6) in the B-Lynch suture group, demonstrating no significant difference (p = 0.563). Furthermore, the length of hospital stay was comparable between the BUAL and B-Lynch suture groups (p = 0.667). Maternal satisfaction, indicated by the proportion of satisfied participants, was high in both groups, with no significant difference observed (p = 0.682). Subgroup analyses based on the mode of delivery and severity of uterine atony within the BUAL and B-Lynch suture groups showed no significant differences in intraoperative blood loss (p-values ranging from 0.491 to 0.802). Conclusion In conclusion, both BUAL and B-Lynch sutures demonstrate comparable efficacy and safety in managing primary postpartum hemorrhage (PPH) due to uterine atony following lower segment cesarean section (LSCS). Further large-scale studies are warranted to validate these findings and inform evidence-based clinical practice in managing PPH during LSCS.
