1 · What the graph read from 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.

2 · The registry

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 a rare clinical condition marked by severe damage and death of the tissue lining the esophagus. During endoscopy, AEN typically presents with a blackened appearance. Risk factors for AEN include esophageal ischemia in the setting of multi-organ dysfunction, sepsis, hypoperfusion, vasculopathy, traumatic transection of the thoracic aorta, thromboembolic phenomena, gastric volvulus, diabetic ketoacidosis, alcohol intoxication, or malignancy. Here, we report a case of AEN diagnosed in a patient presenting with dyspnea and diabetic ketoacidosis who had not been diagnosed with diabetes mellitus previously.
