The Burden of Laryngeal Cleft in Children With Refractory Asthma: A 10-Year Multicenter Experience.
Observational study in Pediatric pulmonology, 2026. 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
introductionUncontrolled asthma and chronic cough are prevalent pediatric respiratory conditions frequently associated with delayed diagnosis of structural anomalies such as laryngeal cleft (LC). LC can exacerbate respiratory symptoms via chronic aspiration and recurrent infections, complicating asthma management. The study objective was to compare demographic and clinical characteristics of children with LC and asthma or chronic cough and evaluate the impact of LC diagnosis and treatment on health care utilization.
methodsRetrospective review of children with LC and uncontrolled asthma or chronic cough across five Nemours Children's Health sites from 2014 to 2024. Patients underwent diagnostic laryngoscopy/bronchoscopy and swallow studies. Health outcomes, including antibiotic and systemic steroid use and respiratory-related hospitalizations, were compared pre- and post-LC treatment. Subgroup analyses were performed for children under and over 2 years old.
resultsAmong 53 patients, children with asthma were significantly older than those without asthma (median age 28.5 months vs. 13 months, p = 0.001). Type 1 LC predominated in both groups. Children with asthma demonstrated greater respiratory health care utilization, more frequent antibiotic use (52% vs. 16%, p = 0.01), and greater hospital admissions. LC treatment reduced antibiotic use but did not significantly reduce overall respiratory health care utilization in children with asthma. Subgroup analyses mirrored full cohort trends, with persistent post-treatment respiratory burden in children with asthma.
conclusionsChildren with asthma and LC demonstrate greater respiratory morbidity and health care utilization, both before and after LC repair. Multidisciplinary care and targeted asthma management remain essential even after anatomical correction.
