Clinical study of bronchial wall area proportion in children and adolescents based on CT images.
Article in BMC pulmonary medicine, 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
objectiveThis study aims to elucidate the distribution and characteristics of bronchial wall area proportion (WA%), defined as [average wall area / (average wall area + average lumen area)], in the lungs of healthy Chinese children and adolescents aged 0-18 years.
methodsIn this cross-sectional retrospective study, chest CT scans from 795 healthy children and adolescents (482 males [61%], 313 females [39%]) aged 0-18 years were analyzed. Participants were stratified into 19 age-specific groups based on sex. Bronchial structures were automatically identified and quantified using a digital pulmonary tracheal branch measurement tool, enabling comprehensive assessment of WA% across all lung segments in the study population.
resultsWA% showed a negative correlation with age in bronchial generations beyond the second airway branch across the pediatric population. This trend was more pronounced in males than females. No significant sex differences in WA% were observed across most age groups (0-15 years, P > 0.05). However, significant differences emerged from age 16 onward in the trachea (generation 0), lung lobes, and upper bronchi (generations 1-2/3), with males consistently exhibiting lower WA% values compared to females (P < 0.05).
conclusionIn children and adolescents aged 0-18 years, bronchial WA% decreases with age. From age 16 onward, sex differences become evident, with males showing lower WA% in the trachea, lung lobes, and upper bronchi compared to females. These findings provide baseline reference data for bronchial wall characteristics in healthy pediatric populations.
