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 colonic pseudo-obstruction (ACPO) and volvulus are two disease processes that affect the colon causing abdominal distension and may necessitate operation intervention. ACPO may be associated with multiple comorbidities, infectious diseases, and cardiac dysfunction. It may be treated with conservative management including endoscopic decompression or neostigmine. If the distension is not addressed, high mortality may result if peritonitis develops. Volvulus most commonly occurs in the sigmoid colon or cecum. If left-sided, endoscopic decompression may resolve the obstruction if detorsion is successful, although sigmoid colectomy should be performed during the admission. If cecal volvulus is identified, right hemicolectomy should be performed.
