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

backgroundPneumoperitoneum is an uncommon condition characterized by free gas in the abdominal cavity, usually resulting from gastrointestinal (GI) tract perforation and requiring emergency surgery. Idiopathic pneumoperitoneum is a rare condition with no identifiable cause and might be managed conservatively in stable patients without peritonitis signs. CASE PRESENTATION: We report two cases of idiopathic pneumoperitoneum diagnosed by Computed tomography (CT) scan without obvious evidence of GI perforation. The etiology remains unclear, the more plausible explanation would be that increased intraluminal or intra-abdominal pressure induced by intestinal obstruction or constipation may contribute to occult micro perforation or mucosal disruption, which may not be detectable on contrast-enhanced CT imaging. The patients exhibited varied clinical presentations and responded well to conservative management, with complete clinical recovery.

conclusionsThis report aims to emphasize the diagnostic challenges in differentiating idiopathic pneumoperitoneum from surgically urgent causes of pneumoperitoneum and to advocate for an appropriate approach to conservative management in stable patients, even when CT imaging demonstrates free intraperitoneal gas.
