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

Ileosigmoid knot (ISK) is a rare, life-threatening cause of intestinal obstruction characterized by a double volvulus involving the ileum and sigmoid colon. This case report highlights distinctive CT findings that facilitate early diagnosis and prompt surgical intervention. A 75-year-old male with chronic constipation and prior midline laparotomy presented with acute bowel obstruction without peritonitis. CT revealed a whirl sign involving both superior and inferior mesenteric artery branches, adjacent ileal loops, and an obliquely oriented torsion, suggestive of ISK. Emergency laparotomy confirmed a Type I ISK, enabling timely detorsion and prophylactic sigmoidectomy before ischemic complications developed. ISK should be suspected when CT demonstrates a whirl sign incorporating both superior and inferior mesenteric artery branches, adjacent ileal loops, and a torsion extending across multiple contiguous slices. These findings distinguish ISK from isolated sigmoid volvulus, guiding appropriate surgical management to optimize outcomes in this rare entity.
