Petersen's Hernia After Roux-en-Y Gastric Bypass: A Case Report.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Internal hernia (IH) is the protrusion of abdominal contents, mostly small bowel loops, through a defect in the peritoneum or mesentery. Petersen's hernia is a type of internal hernia, in which part of the intestinal loop protrudes through a defect between small bowel limbs, transverse mesocolon, and retroperitoneum. It has been reported in individuals undergoing gastrojejunostomy (GJ), especially following bariatric surgeries. Because of the expanding popularity of these surgical treatments, the total incidence of internal hernias has recently increased. The laparoscopic Roux-en-Y gastric bypass (RYGB) has been proven to be a safe and successful alternative to the classic open RYGB. Although the absence of postoperative adhesions is one advantage of minimally invasive surgery, it facilitates the occurrence of internal hernia with reported rates of 5% three months to three years following surgery. Clinical findings are vague and can vary from mild to severe abdominal pain that can be accompanied by vomiting, nausea, and abdominal distention.
