Double Closed-Loop Obstruction Caused by Right Paraduodenal Hernia With Intestinal Malrotation.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Double closed-loop (DCL) obstruction is a rare but diagnostically important computed tomography (CT) finding observed in a subset of strangulated intestinal obstructions. A man in his 40s presented with sudden abdominal pain. CT demonstrated two simultaneous closed loop obstructions with a sac-like appearance, along with the superior mesenteric vein (SMV) rotation sign and absence of the duodenal horizontal segment, leading to a preoperative diagnosis of right paraduodenal hernia (RPDH) with intestinal malrotation. Emergency laparotomy was performed within three hours. Two closed loops of small bowel formed simultaneously, one inside and one outside a 3 cm hernial orifice on the dorsal ileocecal mesentery. Both loops resolved after reduction; the orifice was repaired without bowel resection. The patient was discharged on postoperative day 8. DCL obstruction is a rare but diagnostically valuable CT finding requiring prompt surgical intervention.
