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

Gastric remnant or duodenal perforation after Roux-en-Y gastric bypass (RYGB) or one-anastomosis gastric bypass (OAGB) is rare and may be missed radiologically. We systematically reviewed PubMed, Scopus, and Web of Science and included 26 reports (34 patients), alongside a video-illustrated late OAGB case. Mean age was 49 years, 73.5% were female, and BMI at presentation was 33.58 kg/m²; 32 events followed RYGB and 2 OAGB, occurring a mean of 118.7 months postoperatively. CT was performed in 79.4% and more often showed free fluid than pneumoperitoneum. Laparoscopy (70.6%) with primary repair with or without omental flap or limited remnant resection achieved source control; no completion gastrectomies or 30-day deaths were reported. Early diagnostic laparoscopy should be considered in septic bypass patients with unexplained free fluid; however, the available evidence is limited to case reports and small case series, so definitive conclusions regarding incidence, comparative risk, or causative mechanisms cannot be drawn.
