"Black Esophagus" or Gurvits Syndrome: A Rare Cause of Upper Gastrointestinal Bleeding in Diabetic Ketoacidosis.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
Black esophagus, also called Gurvits syndrome or acute esophageal necrosis (AEN), is a rare, life-threatening condition characterized by necrosis of the esophageal mucosa. We present a 36-year-old man who presented with hematemesis and was admitted for diabetic ketoacidosis (DKA) management. He then had a further episode of hematemesis with hemodynamic instability. The esophagogastroduodenoscopy (EGD) revealed ulcerative, necrotizing, circumferential esophagitis in the middle and distal third of the esophagus. The patient was treated with intravenous fluid resuscitation, proton pump inhibitors, empiric antibiotics, and antifungals. Hematemesis in DKA should raise suspicion for black esophagus. Prompt detection of AEN allows for early management and thus reduces mortality and associated complications such as perforations and strictures.
