Variations in the origin of the right gastric artery: a systematic review and meta-analysis.

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
purposeThe right gastric artery (RGA) supplies the lesser curvature of the stomach. The prevalence of variations in RGA origins can be of interests to students, surgeons, and radiologists who wish to increase their understanding of this vessel. The aim of this study was to perform a systematic review and meta-analysis on the origin of the RGA.
methodsThe PRISMA 2020 checklist was followed. Electronic databases, currently registered studies, conference proceedings and the reference lists of included studies were searched. There were no constraints based on language or publication status. Database search, data extraction and risk of bias assessment were performed independently by two authors. A random-effects meta-analysis of the prevalence of different RGA origins was conducted.
resultsA total of 9084 records were screened in the initial search. Fifteen studies were included, assessing 1971 right gastric arteries. The RGA arose most frequently from the Proper Hepatic Artery (PHA), with a pooled prevalence of 53.6% (95% CI 44.5-60.8%), followed by the Left Hepatic Artery (LHA) with a pooled prevalence of 25.9% (95% CI 18.6-32.8%), and the Gastroduodenal Artery (GDA) with a pooled prevalence of 8.89% (95% CI 4.62-13.9%). Less common origins were the Common Hepatic Artery (CHA) (6.86%, 95% CI 3.15-11.5%), the Right Hepatic Artery (RHA) (3.43%, 95% CI 0.93-7.04%), and Middle Hepatic Artery (MHA) (1.31%, 95% CI 0-3.44%).
conclusionsThis meta-analysis provides an accurate estimate of the prevalence of different RGA origins. Anatomical knowledge combined with pre-operative planning and imaging can prevent iatrogenic injury during surgery.
