Idiopathic pneumoperitoneum, a possible complication of pure oxygen administration in a neonate with laryngomalacia: a 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 clinical importance: Idiopathic pneumoperitoneum can occur in a full-term neonate due to the administration of pure oxygen. Recognition of this rare mechanism is necessary to avoid unnecessary surgical exploration. Case presentation: We report the case of a six-day-old male neonate with a history of respiratory distress and non-invasive pure oxygen support (FiO Clinical discussion: Idiopathic pneumoperitoneum should be suspected in neonates with a history of respiratory distress but without classic clinical signs of peritonitis. Notably, noninvasive administration of pure oxygen alone can cause idiopathic pneumoperitoneum. Conclusion: In a full-term neonate, non-invasive administration of pure oxygen for laryngomalacia can cause idiopathic pneumoperitoneum, which may have a favorable outcome with conservative management.
