Total immunoglobulin E levels in induced sputum reflect asthma control status.
Article in Clinical and translational allergy, 2025. 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
backgroundMost patients with severe asthma are sensitized to at least one allergen. Whether local immunoglobulin E (IgE) in induced sputum reflects asthma control status has not been investigated.
methodsPatients with asthma were classified as well controlled, partly controlled, and uncontrolled asthma (UCA) according to Global Initiative for Asthma 2022 guidelines. Lung function and fractional exhaled nitric oxide (FeNO) were evaluated. Induced sputum was collected and total IgE and Phadiatop (IgE to common inhalant allergens) measurements were performed. General clinical characteristics and pulmonary inflammation indicators were analyzed between the three groups of asthmatic patients. Univariate and multifactor ordinal logistic regression were used to model the relationship between pulmonary inflammation indicators and asthma control status. The ability of sputum total IgE in identifying different levels of asthma control was assessed by receiver operating characteristic curve (ROC).
resultsPatients with UCA had worse lung function and airway inflammation as indicated by lower levels of forced expiratory volume in 1s (FEV1)%pred, FEV1/FVC, MEF75%pred, MEF50%pred and MEF25%pred, and higher levels of FeNO and sputum eosinophil% compared with the WCA group. In addition, higher levels of total sputum IgE and Phadiatop were found in patients with UCA than in patients with WCA and PCA. Univariate and multifactor ordinal logistic regression analysis indicated that sputum total IgE was the unique significant risk factor for poor asthma control (adjusted odds ratio = 6.25; 95% CI, 1.07-36.55; p < 0.05) among pulmonary inflammation indicators including different indices of pulmonary function test, sputum IgE and FeNO. Sputum total IgE levels showed a significant correlation with asthma control scores (r = 0.53, p < 0.001). Moreover, ROC analysis showed that the predictive value of sputum total IgE for patients with UCA was 0.82 (95% CI, 0.74-0.9).
conclusionSputum total IgE reflects levels of asthma control, and can be used as an indicator of UCA.
