Relation of changes in PEF and FEV
Article in European clinical respiratory journal, 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
introductionAsthma diagnosis can be confirmed through the observation of significant bronchodilator response (BDR) measured by peak expiratory flow (PEF) during home monitoring or by forced expiratory volume in one second (FEV
aimTo use salbutamol administration after an exercise challenge test in children as a model of bronchodilation to assess how well relative change in PEF reflects improvement in lung function, as defined by increase in FEV
methodsWe retrospectively studied 326 free running exercise challenge tests with spirometry in children 6-16 years old. To assess congruency and differences between relative changes in PEF and FEV
resultsRelative change in PEF was, on average, greater than that in FEV
conclusionIncrease in PEF is not an accurate measure of BDR compared with increase in FEV
