Challenges faced by adolescents and lung function technicians in Anuradhapura district, Sri Lanka, during spirometry: a qualitative study.
Article in International health, 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
backgroundSpirometry is the gold standard test for diagnosing airway disease. However, conducting spirometry in adolescents (13-14 y of age) is challenging because technicians should build a good rapport and maintain the technical rigour required in adult testing. This study investigated the challenges in spirometry assessment of adolescents with severe asthma.
methodsThis was a qualitative descriptive study conducted in the Anuradhapura district, Sri Lanka from February to April 2023. Spirometry was conducted according to standard American Thoracic Society/European Respiratory Society guidelines. Three instructors with adequate knowledge but no prior experience conducted spirometry in adolescents, while two independent researchers observed the participants, followed by in-depth interviews. Data were collected until data saturation was achieved. Thematic analysis was used to analyse the experiences and perspectives of lung function technicians and participants.
resultsData saturation was achieved with 15 adolescents (7 male, 8 female). Two (13.3%) participants showed airway obstruction, while one (6.67%) had significant reversibility. Demonstration and simultaneous execution to train the respiratory manoeuvres improved the responses, but the test was tiring for the trainee instructor. Most adolescents found the procedure exhausting, and the trainee instructor's self-confidence improved the adolescents' performance.
conclusionsThe study underscores the need for specialized training required to conduct spirometry in adolescents and better awareness for adolescents and parents of lung function testing.
