Pediatric Sharp Foreign Body Aspiration: Revealing Unexpected Risk Factors.
Article in Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveCharacterize the demographic and clinical features of pediatric sharp foreign body aspiration (FBA). STUDY
designTwenty-four-year retrospective chart review.
settingFour tertiary-care centers across four Canadian provinces.
methodsA retrospective chart review was conducted on pediatric patients who underwent rigid bronchoscopy for sharp FBA below the vocal cords at the McGill University, McMaster University, University of Alberta, and Dalhousie health centers from January 1, 2000, to November 30, 2023.
resultsIn total, 48 patients (27 males and 21 females, mean age of 10.1 years) met the inclusion criteria. Thumbtacks were the most common aspirated objects (66.7%). The mean age for thumbtack aspiration was 11.6 years, which was significantly higher than the 7.0-year mean for other sharp FBAs (P = .0263). Subgroup analysis of patients who resided in an Indigenous territory had a significantly greater rate of thumbtack aspiration (89.3%, P = .0001). Sharp FBA presented with typical symptoms of FBA with the addition of a higher incidence of chest pain (27.1%) and hemoptysis (18.8%), and it was characterized by a higher incidence of radiopaque FBs on chest radiography (89.6%). Most complications, including postoperative atelectasis (27.1%), pneumothorax (4.2%), perforation (2.1%), and vocal cord hematoma (2.1%), were observed with thumbtacks.
conclusionThis is the largest pediatric study on sharp FBA in America, addressing a significant gap in the literature. Considering the trends and patient demographics identified in this study and in the literature globally, geographical or cultural variations may influence the nature of sharp FBA in pediatric populations. Insights from this study can inform future prevention programs.
