Assessment of Bronchodilator Responsiveness and Spirometric Patterns in Patients with Rhinitis and Suspected Asthma.
Article in Journal of asthma and allergy, 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
Background: Bronchodilation testing (BDT) is routinely used to assess reversibility of airflow limitation. For patients with rhinitis who report asthma-related symptoms but often show preserved spirometry, the clinical patterns associated with bronchodilator responsiveness (BDR) are less clearly described. Understanding these patterns may help clinicians interpret lung function in real-world practice. Methods: We retrospectively analyzed 555 consecutive patients who underwent spirometry and BDT at a single tertiary allergy center. Data on clinical symptoms, allergic status, type-2 inflammatory markers, baseline spirometry results, and BDT outcomes were collected. Associations between symptoms, spirometric indices, and BDR were evaluated. Exploratory analyses examined the relationship between FEV Results: Among all participants, 71.9% had allergic rhinitis, and 88.6% reported asthma-related symptoms. BDR was observed across a wide range of baseline spirometry values; 47.2% of BDT-positive patients had FEV Conclusion: In patients with rhinitis and suspected asthma, airflow variability may be present even when FEV
