Mepolizumab Effectiveness in Severe Asthma With/Without Chronic Rhinosinusitis With Nasal Polyps: Real-World Pooled Analysis.
Article in Allergy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundSevere asthma with an eosinophilic phenotype (SAEP) and chronic rhinosinusitis with nasal polyps (CRSwNP) are predominantly type 2-driven diseases, characterised by eosinophilic inflammation and substantial disease burden. Mepolizumab, a humanised monoclonal antibody that targets interleukin-5, a key cytokine in type 2 inflammation, is an effective, approved treatment both in SAEP and CRSwNP. We aimed to analyse real-world evidence of mepolizumab effectiveness in patients with comorbid SAEP and CRSwNP.
methodsThis study pooled five existing, predominantly European cohorts to describe the impact of mepolizumab on the rate of clinically significant exacerbations (CSEs) and other outcomes in adults with SAEP without and with comorbid CRSwNP (SAEP[-]CRSwNP and SAEP[+]CRSwNP, respectively).
resultsOverall, 1037 patients were included. Baseline characteristics were similar in both cohorts. Mepolizumab was associated with a reduction from baseline in the annual rate of CSEs at 12-months post-initiation (SAEP[-]CRSwNP: 72.7%; SAEP[+]CRSwNP: 79.7%), irrespective of baseline blood eosinophil count (BEC). When patients with SAEP[+]CRSwNP were compared with patients with SAEP[-]CRSwNP, a 30.0% incremental benefit in the reduction of CSEs was observed. At 12-months post-initiation, mepolizumab was also associated with a reduction in oral corticosteroid use and BEC, and an improvement in lung function and Asthma Control Test (ACT) scores in both cohorts. Post-mepolizumab initiation, ≥ 3 clinical remission criteria were fulfilled by 47.2% and 52.3% of patients with SAEP[-]CRSwNP and SAEP[+]CRSwNP, respectively.
conclusionsThe results provide a greater understanding of mepolizumab's effectiveness, demonstrating a substantial improvement in asthma outcomes, irrespective of baseline BEC and the presence of comorbid CRSwNP.
