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
backgroundSingle-balloon enteroscopy (SBE) is an established procedure for evaluating small bowel lesions. While its efficacy is well recognized, the incidence of major complications and their associated risk factors in a large population remain unclear.
aimTo investigate the complications and risk factors associated with diagnostic SBE.
methodsThis multicenter retrospective study included consecutive patients who underwent diagnostic SBE at three tertiary care hospitals between January 2016 and September 2024. Data on baseline characteristics, procedural parameters, indications, findings, and major complications were collected and analyzed.
resultsA total of 2865 SBE procedures were performed in 1840 patients. The mean age was 51 ± 18 years, and 64.5% were male. The most common indication was obscure gastrointestinal bleeding (57.1%), followed by abdominal pain (30.5%). The major complication rate was 0.4% (7/1840), all of which involved acute intestinal perforation identified during the procedure. Among the perforation cases, 6 occurred in patients undergoing SBE for abdominal pain and 1 for obscure gastrointestinal bleeding. The perforation sites included the ileum (6/7) and duodenum (1/7). All cases were successfully managed surgically. Previous abdominal surgery and the use of abdominal compression were significantly associated with an increased risk of perforation (
conclusionAcute intestinal perforation is a rare but serious complication. Prior abdominal surgery and abdominal compression are important risk factors, and careful patient selection is recommended to minimize complications.
