Natural History of Airway Hyperresponsiveness and Its Association With Asthma Traits.
Article in Allergy, 2026. 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 natural history of airway hyperresponsiveness (AHR) from childhood to adulthood and its association with asthma status are poorly understood. We aim to define the natural history of AHR in relation to asthma characteristics such as symptoms, atopy and lung function to improve our understanding of the changes in AHR with asthma pathophysiology during adolescence.
methodsMethacholine bronchial challenge test (BCT) was undertaken in the Isle of Wight whole population birth cohort at 10 years (n = 783), 18 years (n = 585) and 26 years (n = 86). Data on wheeze, lung function, and atopy were collected at each time point. Definite AHR was defined as methacholine concentration provoking a 20% decrease in Forced Expiratory Volume in 1 s (PC
resultsAHR prevalence was 21.6% (169/783) at 10 years and 5% (29/585) at 18 years of age (p < 0.01). In 406 participants, where methacholine BCT was performed at both 10 and 18 years, 80.9% of those with AHR at age 10 became negative at 18 years. At a population level, AHR trajectory was in the opposite direction to that of asthma (14.7% at age 10 to 17.6% at age 18; p = 0.004), atopy (26.9% at age 10 to 41.5% at age 18; p < 0.001) and airway obstruction (FEV
conclusionThe natural history of AHR is characterised by a marked decrease in prevalence during adolescence, in contrast to asthma and other asthma characteristics. Age should be considered when interpreting AHR as an asthma defining trait.
