Asthma control and sputum eosinophils in adult patients: a cross-sectional study in southern Brazil.
Article in Scientific reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Asthma control and health related quality of life are an important goal of asthma management, but their association with sputum eosinophilic inflammation has been less firmly established. To investigate the relationship of asthma control and quality of life with sputum eosinophils in clinical practice. Cross-sectional study with a convenience sample, including patients with asthma, aged between 18 and 65 years, attending to outpatient clinic. Patients underwent sputum induction, pulmonary function tests, Juniper's Asthma Quality of Life Questionnaire (AQLQ), Asthma Control Test (ACT), Global Initiative for Asthma (GINA) criteria for evaluation of asthma control and severity of the disease, blood count analysis, serum IgE and cutaneous prick test. Sputum sample was considered as eosinophilic if the percentage of eosinophils was ≥ 3%. A total of 45 individuals were enrolled, 15 with eosinophilic sputum (≥ 3% eosinophil cells) and 30 with non-eosinophilic sputum (< 3% eosinophil cells). There were no association of ACT an AQLQ scores with sputum eosinophilia (p > 0.05). This study suggested that the finding of sputum eosinophilia was not related to asthma control neither with health-related quality of life in patients with severe asthma.
