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
We report a rare case of retrograde duodenojejunal intussusception caused by Ladd's bands in an adult with intestinal malrotation. A 27-year-old man with a history of cerebral palsy and gastrostomy presented with frequent vomiting. Abdominal contrast-enhanced computed tomography showed marked distention of the stomach and duodenum, along with retrograde intussusception of the jejunum into the duodenum at the horizontal segment. No neoplastic lesions were identified as a lead point. A diagnosis of intestinal obstruction due to retrograde intussusception was made, and emergency laparoscopic surgery was performed. Intraoperative findings revealed nonrotation-type intestinal malrotation. The duodenum was not fixed to the retroperitoneum, and a thickened Ladd's band was pulling the duodenum ventrally. This mechanical traction caused the mobile jejunum to invaginate retrogradely into the duodenum. Transection of the Ladd's band released the traction, resulting in spontaneous reduction of the intussusception. No ischemic changes were observed in the intestine, and the postoperative course was uneventful. Retrograde intussusception in adults is extremely rare and is typically caused by organic lesions or postoperative factors. In this case, mechanical traction by Ladd's bands combined with intestinal mobility due to malrotation was considered the primary cause. Laparoscopic surgery was effective for both definitive diagnosis and minimally invasive treatment.
