Congenital non-parasitic hepatic cyst complicated by hepatoduodenal fistula: a rare case report.

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
Introduction and importance: Simple hepatic cysts are benign and usually asymptomatic; however, they can rarely develop serious complications, such as hepatoduodenal fistula, due to infection, cyst size, or mechanical pressure. Case presentation: A 68-year-old male presented with fever, hematochezia, and severe right upper quadrant pain. Imaging revealed a 10 × 12 cm segment V-VII hepatic cyst with an air-fluid level, and endoscopy showed a fistulous opening in the second duodenum adjacent to a necrotic diverticulum. After stabilization, laparotomy confirmed a hepatoduodenal fistula; a 2 cm opening was closed with an omental patch, the cyst was deroofed, and a drain was placed, resulting in excellent recovery. Clinical discussion: This rare hepatoduodenal fistula arose from an infected simple hepatic cyst (pathology: cuboidal epithelium; negative Conclusion: Infected simple hepatic cysts can rarely progress to a hepatoduodenal fistula with significant morbidity, but prompt diagnosis, resuscitation, antibiotics, and definitive surgical repair can result in full recovery.
