Control Status of Chronic Rhinosinusitis in Severe Asthma Patients Receiving Biologics: A Real-World Cross-Sectional Study.
Observational study in The Annals of otology, rhinology, and laryngology, 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
objectiveThis study aimed to determine the prevalence, subtypes, and control status of chronic rhinosinusitis (CRS) among patients with severe asthma receiving biologic therapy in a tertiary allergy clinic.
methodsA single-center, cross-sectional observational study was conducted in adult patients with severe asthma receiving biologics for at least 6 months. CRS diagnosis and control were assessed based on European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2020 criteria. The Sinonasal Outcome Test-22 (SNOT-22) was also administered. Statistical analyses were performed using appropriate univariate and multivariate methods.
resultsAmong 148 patients with severe asthma receiving biologic therapy, 97 (65.5%) were diagnosed with comorbid CRS. Of these, 68 (45.9%) had CRS with nasal polyps (CRSwNP) and 29 (19.5%) had CRS without nasal polyps (CRSsNP). A total of 54 patients (55.6%) were treated with omalizumab and 43 (44.3%) with mepolizumab. Overall, 32.9% of patients had controlled CRS, 36.0% were partly controlled, and 30.9% were uncontrolled. In multivariable ordinal regression analysis, the presence of N-ERD and higher BMI were associated with poorer CRS control, whereas early-onset asthma and prior maintenance systemic corticosteroid use were associated with better control, suggesting that these factors may be related to CRS control status in this population.
conclusionsCRS is highly prevalent among patients with severe asthma receiving biologics, and approximately one-third remain uncontrolled despite treatment. These findings emphasize the importance of regular upper airway assessment and may inform future strategies for optimizing biologic selection and treatment outcomes in this population.
