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

introductionRetrograde colonic intussusception is a rare condition in adults, often caused by organic lesions such as tumors. Autonomic dysfunction in disorders like multiple system atrophy (MSA) might contribute to its occurrence. CASE PRESENTATION: An 81-year-old bedridden woman with a history of MSA presented with severe abdominal pain and abdominal distension lasting 4 days. She had chronic severe constipation managed with laxatives and manual disimpaction. CT imaging revealed retrograde intussusception of the rectum into the sigmoid colon. Endoscopic reduction was attempted but was unsuccessful due to scope impassability. Emergency laparotomy identified a 4-5 cm tumor at the lead point, and manual reduction resulted in bowel perforation. Hartmann's procedure with D2 lymphadenectomy was performed. The tumor was histopathologically diagnosed as a tubulovillous adenoma with no malignant features. The patient's postoperative recovery was uneventful except for a urinary tract infection (Clavien-Dindo Grade II), and she was transferred to a rehabilitation facility on postoperative day 24.

conclusionFailure of reduction by air enema should raise suspicion for retrograde intussusception, warranting prompt surgery if an organic lead point is suspected.
