The Effect of Inhaled Oxygen on Postpartum Hemorrhage: A Systematic Review and Meta-Analysis.
Review in Iranian journal of nursing and midwifery research. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Postpartum Hemorrhage (PPH) is a significant problem that can increase the risk of maternal mortality. Previous studies investigated the effect of Inhaled Oxygen (IO) on PPH. They found some conflicting results. Thus, the current systematic review and meta-analysis aimed to determine the effect of IO on PPH. Materials and Methods: Randomized trials were searched according to the PRISMA framework until the end of November 2022 in Web of Science, PubMed, Scopus, and Cochrane Library databases. Statistical analyses were performed in the STATA v. 14 software. I Results: Results showed that IO significantly reduced bleeding by 38.91 mL in the intervention group compared to routine care (WMD: -38.91, 95%CI: -60.18 to -17.64) after vaginal delivery. In addition, IO during one (WMD: -38.42, 95%CI: -71.62 to -5.22) and two (WMD: -41.93, 95%CI: -60.15 to - 23.71) hours significantly decreased bleeding in the intervention. Conclusion: According to the present study, IO can significantly reduce PPH in the intervention group compared to routine care. However, more rigorously randomized clinical trials are required to decide better about this issue.
