Median arcuate ligament syndrome with anomalous origin of the right inferior phrenic artery from the celiac artery: a case report.
Article in Frontiers in surgery, 2026. 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
Median arcuate ligament syndrome (MALS) is a rare vascular disorder. We report the case of a 72-year-old man with MALS who was found to have an anomalous right inferior phrenic artery originating from the celiac artery (CA), which was not detected on preoperative computed tomography angiography. During laparoscopic decompression, this vessel was encountered unexpectedly. A temporary clamping test was performed, confirming no diaphragmatic or hepatic ischemia, after which the vessel was safely ligated. The CA was then fully decompressed. Postoperatively, the patient's symptoms resolved completely. This case underscores that significant vascular anomalies may only be revealed intraoperatively. The described clamping technique provides a simple and safe method for real-time functional assessment, aiding critical surgical decisions when managing unforeseen anatomical variations.
