Diagnostic yield of bronchoscopy in children with leukemia or post hematopoietic stem cell transplant.
Article in Pediatric pulmonology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe utility of bronchoscopy with bronchoalveolar lavage (BAL) in immunocompromised children is not well understood. We aim to describe the bronchoscopy diagnostic yield and complications and to investigate factors associated with diagnostic yield.
methodsThis is a single-center, retrospective cohort study of 60 children with leukemia or post-hematopoietic stem cell transplant who had a bronchoscopy with BAL between 2017 and 2021. Comparisons were done with regression analysis.
resultsOf the 60 bronchoscopies performed, 46 (77%) revealed diagnostic information: 39 (65%) identified a pathogen, 14 (23.3%) found secretions/mucus plugging, and 6 (10%) found pulmonary hemorrhage. BAL results changed antimicrobial therapy in 27 (45%) cases. Bronchoscopies were performed in the intensive care unit (27/60) or operating room (33/60), with the former having a higher diagnostic yield (96% vs. 60%, p = 0.001). Half (50%) of bronchoscopies found a new infectious diagnosis. Respiratory symptoms (n = 58, 97%), supplemental oxygen use (n = 39, 65%), and antibiotic use (n = 56, 93%) before bronchoscopy were all common. The median volume of fluid instilled during bronchoscopy was 1.3 mL/kg (interquatile range [IQR]: 0.7, 2.6). None of these factors were associated with the diagnostic yield. Complications were rare and minor with only one child having self-resolved bleeding and four children, previously in room air requiring a nasal cannula. For the 27 (45%) children on mechanical ventilation when the bronchoscopy was performed, there was no difference in ventilator settings pre- and post-bronchoscopy.
conclusionBronchoscopies with BAL are useful, safe, and important in the diagnostic management of pulmonary complications in this cohort of children.
