Effectiveness of biologics for patients with severe asthma: study protocol for an umbrella review of systematic reviews and meta-analyses.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionMany systematic reviews and meta-analyses (SRs/MAs) have evaluated the efficacy of biologic therapies for severe asthma. However, the overall quality of these SRs/MAs is unclear, which may influence the selection of biologics and lead to misleading clinical decisions. This umbrella review aims to objectively evaluate the overall quality of these SRs/MAs and reassess the efficacy of biologic therapies for severe asthma. Thus, this study will provide reliable evidence for clinical practice. METHODS AND ANALYSIS: A systematic search will be performed in PubMed, Embase, Cochrane Library, Web of Science, Scopus and conference abstracts up to 1 March 2025. Literature screening and data extraction will be conducted according to predefined inclusion and exclusion criteria. We will evaluate the reporting quality, methodological quality and evidence quality of these SRs/MAs using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement, PRISMA for Network Meta-Analysis 2015 checklist, A MeaSurement Tool to Assess Systematic Reviews 2, Cochrane Risk of Bias 1.0 and Grading of Recommendations Assessment, Development and Evaluation system. Additionally, the re-analysis of outcomes will be performed using R software (V.4.3.3). ETHICS AND DISSEMINATION: Since this umbrella review will use publicly available data, ethics approval is not required. The results of this study will be disseminated through publication in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42024607393.
