Functional Exercise Capacity and Exploratory ICF-Aligned Interpretation of the Incremental Shuttle Walk Test in Children With Asthma.

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
backgroundChildren with asthma may experience functional exercise limitations that are not fully reflected by resting lung function or conventional clinical assessments. Field-based exercise tests provide complementary information regarding functional capacity, and the International Classification of Functioning, Disability and Health (ICF) offers a biopsychosocial framework to contextualize activity limitations. However, the integration of objective exercise performance with ICF-aligned interpretation in pediatric asthma remains limited.
objectiveTo interpret functional exercise capacity in children with asthma using Incremental Shuttle Walk Test (ISWT) performance through an exploratory operational framework conceptually aligned with ICF activity qualifiers and to examine its association with lung function, asthma control, quality of life, and demographic characteristics.
methodsIn this cross-sectional study, 39 children with asthma (mean age 8.6 ± 2.3 years) underwent spirometry, completed the Asthma Control Questionnaire (ACQ-6) and the Pediatric Asthma Quality of Life Questionnaire (PAQLQ), and performed the ISWT. Functional exercise capacity was expressed as a percentage of predicted ISWT distance and interpreted using an exploratory operational framework conceptually aligned with generic ICF activity qualifiers, generating two categories of activity limitation (mild/moderate and severe).
resultsResting lung function was relatively preserved (mean FEV
conclusionChildren with asthma may present substantial functional exercise limitations despite relatively preserved lung function and similar levels of asthma control and quality of life. The exploratory operational alignment of ISWT performance with generic ICF activity qualifiers may provide a clinically useful framework to support interpretation of activity limitations not captured by conventional assessments. However, this approach should be interpreted cautiously and requires future validation before broader clinical application.
