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
backgroundForeign body aspiration (FBA) in children is a potentially life-threatening event, especially in those under 3 years of age. This study aimed to identify clinical factors associated with hospitalization in pediatric FBA and to highlight innovative retrieval methods used in a tertiary care setting.
methodsA retrospective analysis was conducted of pediatric patients (< 18 years) presenting with confirmed airway FBA between January 2015 and September 2023 at Srinagarind Hospital, Khon Kaen University. Demographic information, clinical characteristics, and procedural data were collected. Univariate and multivariate logistic regression analyses identified predictors of hospitalization.
resultsAmong 297 pediatric patients with FBA, 39 (13.1%) required hospitalization. Hospitalized children were younger (median age: 3 years; interquartile range [IQR] 2-7) compared with non-hospitalized children (median age: 4 years; IQR 3-7, p = 0.018). FBA involving the larynx-trachea-bronchus significantly increased the likelihood of admission (adjusted odds ratio [AOR] = 22.0; 95% confidence interval [CI]: 6.64-72.63; p < 0.001). Delayed presentation to the emergency department more than two hours after onset was also associated with hospitalization (OR = 2.77; 95% CI: 1.08-7.09; p = 0.033). Although rigid bronchoscopy remained the mainstay treatment, flexible bronchoscopy was successfully utilized in nine cases. Notably, a novel technique using a 3 mm gold-plated neodymium magnet under fluoroscopic guidance enabled the safe retrieval of distal metallic foreign bodies. Complete removal of the aspirated objects was achieved in all patients; however, one patient died following prolonged hypoxia prior to hospital arrival.
conclusionsYounger age, delayed emergency department presentation, and location of the foreign body in the larynx-trachea-bronchus are significant predictors of hospitalization in pediatric FBA. Rigid bronchoscopy remains the primary management strategy, while flexible bronchoscopy and innovative retrieval methods, including magnet-assisted approaches, offer effective alternatives in specific scenarios. Emphasizing early diagnosis and rapid intervention is essential to reduce complications and improve outcomes in children with FBA.
