Acute Esophageal Necrosis in a Patient With Septic Shock and Advanced Kidney Disease: A Case Report and Literature Review.
Article in Cureus, 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
Acute esophageal necrosis (AEN), also known as black esophagus, is an uncommon yet life-threatening condition characterized by diffuse circumferential esophageal necrosis, most commonly associated with states of systemic hypoperfusion. We report a case of a 73-year-old male with multiple comorbidities, who developed AEN in the setting of septic shock, advanced chronic kidney disease with acute deterioration of renal function, and severe electrolyte disturbances. The diagnosis was established by upper gastrointestinal endoscopy, which revealed extensive esophageal necrosis with characteristic endoscopic findings. Despite intensive supportive care and multidisciplinary management, the patient experienced progressive clinical deterioration and ultimately died. This case highlights the synergistic contribution of septic shock, advanced renal dysfunction, severe metabolic abnormalities, and refusal of renal replacement therapy to the development of fulminant AEN. It underscores the importance of maintaining a high index of suspicion for AEN in critically ill patients with gastrointestinal bleeding and multiple comorbidities while providing a contemporary review of its pathophysiology, prognostic factors, and clinical outcomes.
