Effectiveness of anti-IL-5/5Rα biologics in severe asthma in real-world studies: a systematic review and meta-analysis.
Article in ERJ open research, 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
Background: Three biologics targeting interleukin 5 (anti-IL-5) or its receptor-α (anti-IL-5Rα) are approved for patients with severe asthma. Methods: We systematically searched the literature published in Medline and Embase up to 1 May 2023 to identify observational studies and nonrandomised trials that assess the response to anti-IL-5/5Rα in real-life patients with severe eosinophilic asthma. We also performed random-effects meta-analyses. Results: We identified 6401 studies, of which 92 with 9546 patients were analysed. Biologics use was associated with a 62% reduction in severe exacerbations (risk ratio 0.38, 95% CI 0.29-0.50) and a 54% reduction in hospitalisations (risk ratio 0.46, 95% CI 0.35-0.61) at 12 months of treatment, compared to pre-treatment. Biologics improved asthma control (decrease in asthma control questionnaire score by 1.11 points (95% CI -1.29--0.94) and increase in asthma control test score by 6.41 points (95% CI 5.66-7.16)) and increased the asthma quality of life questionnaire score by 1.08 points (95% CI 0.88-1.28) and forced expiratory volume in 1 s by 0.21 L (95% CI 0.15-0.27) at 12 months. There was a significant reduction in oral corticosteroids use of 51% (risk ratio 0.49, 95% CI 0.42-0.56), with a mean dose reduction of 6.01 mg·day Conclusions: This comprehensive meta-analysis summarises the significant clinical response to anti-IL-5/5Rα biologics in real-life studies, providing important insights for their use in clinical practice.
