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
BACKGROUND/
objectivesBezoars are described as masses of undigested substances that can be found within the gastrointestinal tract. This study aimed to explore the types of bezoars observed in pediatric patients and examine the underlying factors contributing to the formation of these bezoars and treatment outcomes.
methodThis retrospective study was conducted at a tertiary medical center in Northern Taiwan from January 2000 to June 2023. We enrolled pediatric patients diagnosed with bezoars in the gastrointestinal tract from the medical database of esophagogastroduodenoscopy, upper gastrointestinal series, lower gastrointestinal series, abdominal computed tomography, and surgical procedural codes. Demographic characteristics, presenting symptoms, imaging findings, and clinical course were reviewed.
resultsA total of 25 patients, including 14 females (56%), with a median age of 12.0 years (interquartile range: 5.9-15.0 years), were enrolled in this study. Phytobezoars were observed in 17 patients, while trichobezoars were found in 5 patients, and 3 patients had lactobezoars. The stomach was identified as the most frequent site. Among these patients, gastrointestinal anomalies were found in 15 patients (60%), with neuropsychiatric disorders in 11 patients (44%). Surgical intervention was required for 14 patients (56%), 5 patients (20%) underwent endoscopic treatment, and 6 patients (24%) passed the bezoar spontaneously. Trichobezoars (100%,
conclusionsPhytobezoars are the predominant type of bezoar observed in children, with gastrointestinal anomalies and neuropsychiatric disorders being potential contributing factors. Patients with trichobezoars or bezoars located in the lower gastrointestinal tract, especially those of larger size, are more likely to require surgery for treatment.
