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
objectiveForeign body aspiration (FBA) is a common pediatric emergency, and bronchoscopy remains the diagnostic and therapeutic gold standard despite its invasive nature and associated procedural risks. This study aimed to evaluate the clinical and radiographic factors associated with foreign body detection during bronchoscopy in children undergoing bronchoscopy for suspected FBA.
methodsThis single-center, retrospective, cross-sectional study included children aged 0-18 years who underwent bronchoscopy for suspected FBA at a tertiary pediatric emergency department between January 2010 and January 2026. Of 120 eligible patients, 25 were excluded because of incomplete medical records, resulting in a final cohort of 95 children. Predictors of bronchoscopy positivity were evaluated using Firth's penalized logistic regression because of outcome imbalance and separation in some radiographic variables.
resultsThe median age was 19.0 months (interquartile range [IQR] 14.0-26.0), and 55 patients (57.9%) were male. Foreign bodies were identified in 81 children (85.3%), whereas bronchoscopy was negative in 14 (14.7%). Air trapping on chest radiography showed the strongest association with foreign body detection during bronchoscopy (adjusted OR 33.80, 95% CI 4.19-4389.05;
conclusionsAmong children undergoing bronchoscopy for suspected FBA, radiographic air trapping showed the strongest association with foreign body detection, although this finding should be interpreted cautiously because of substantial statistical uncertainty. A normal chest radiograph could not reliably exclude FBA, and individual clinical findings showed limited discriminatory value. These findings apply only to children who had already been selected for bronchoscopy and support integrating clinical history, physical examination, and imaging findings when evaluating such patients.
