Effectiveness of Mepolizumab in Patients with OCS-Dependent Severe Asthma: A Real-World Study.
Observational study in Advances in therapy, 2025. 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
introductionBefore the availability of biologic therapies, the main treatment for patients with severe asthma in Asia, Latin America, and the Middle East was oral corticosteroids (OCS), despite long-term use causing serious adverse effects. This post hoc analysis of the NUCALA Effectiveness Study (NEST) evaluated the effectiveness of mepolizumab, an anti-interleukin-5 monoclonal antibody, in patients with severe asthma and OCS dependence from regions with limited representation in real-world studies.
methodsNEST was a multicountry, observational cohort study in adults with severe asthma from Colombia, Chile, India, Türkiye, Saudi Arabia, United Arab Emirates, Kuwait, Oman, and Qatar. Patients received ≥ 1 dose of 100 mg mepolizumab. OCS dependence was defined as receiving maintenance OCS at mepolizumab initiation or for ≥ 26 weeks during the 12 months prior. Data were collected 12 months pre- and post-initiation. Outcomes included OCS use, rate of clinically significant exacerbations (CSEs), and level of asthma symptom control.
resultsOf 524 patients with OCS use data, 58.4% (n = 306) had OCS dependence pre-initiation. Mean (standard deviation) age was 49.2 (13.4) years; 73.9% (n = 226) were women. Of 251 patients with available data, 87.6% (n = 220) received lower OCS doses post-initiation and 68.9% (n = 173) stopped OCS use altogether. CSEs were reduced by 76.9% post-initiation. Of 222 patients with available data, 72.5% (n = 161) had improvements in Asthma Control Test scores post-initiation.
conclusionIn patients with severe asthma and OCS dependence from the countries studied, mepolizumab reduced OCS use and dose, asthma exacerbations, and improved symptom control.
