Retroperitoneal hemorrhage due to ruptured artery induced by median arcuate ligament syndrome in patients with COVID-19: A case series.
Article in Acute medicine & surgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Median arcuate ligament syndrome describes a clinical presentation associated with direct compression of the celiac artery by the median arcuate ligament. Decreased blood flow from the celiac artery and increased flow from superior mesenteric artery causes blood flow in the pancreatic arcade to increase, and aneurysms can form. We report our experience with six cases of retroperitoneal hemorrhage induced by median arcuate ligament syndrome in patients during the COVID-19 period. Case Presentation: The time from the onset of COVID-19 to that of abdominal pain in the patients ranged from 3 to 9 days. None of the patients required oxygen for COVID-19. We used contrast-enhanced computed tomography to diagnose retroperitoneal hemorrhage and formation of a visceral pseudoaneurysm or aneurysm due to median arcuate ligament syndrome. Five patients underwent transcatheter arterial embolization. One patient suffered complications of duodenal stenosis and another suffered portal vein thrombosis. Conclusions: Retroperitoneal hemorrhage associated with median arcuate ligament syndrome is rare. However, it might be triggered by COVID-19 disease, resulting in arterial disruption and hemorrhage.
