Causal Relationships Between Immune Cell Traits, Plasma Metabolites, and Asthma: A Two-Step, Two-Sample Mendelian Randomization Study.
Article in The clinical respiratory journal, 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
backgroundConsiderable evidence suggests a strong link between immune cell traits (ICTs) and asthma development via plasma metabolites (PMs), but the causality between ICTs and asthma is still unclear, mainly due to issues like selection bias. Our research was designed to investigate the causality between ICTs, PMs, and asthma and to provide a clearer explanation of these relationships.
methodsUtilizing the GWAS database, this study employed a two-step, two-sample Mendelian randomization (MR) approach and the inverse variance weighted (IVW) method to investigate the causality between ICTs and asthma, as well as between PMs and asthma. Lastly, we calculated the mediated proportion of PMs as mediators in the link between ICTs and asthma.
resultsExcluding heterogeneity and pleiotropy, MR analysis identified 13 ICTs (CD14 on CD33br HLA DR+ CD14dim, etc.) and asthma causality, and no reverse causality was observed. In addition, 27 PMs (androsterone sulfate levels, succinate levels, etc.) were also causally associated with asthma. Mediate MR indicated -9.81% (-1.2%, -18.4%) of the effect of CD24 on IgD+ CD38br on asthma is mediated by S-methylcysteine sulfoxide levels, with a mediated effect value (p = 0.006) is 0.003 (0.0004, 0.006); 21.4% (6.2%, -36.6%) of the effect of CD3 on CD28+ CD4+ on asthma is mediated by 1-myristoyl-2-arachidonoyl-GPC (14:0/20:4) levels, with a mediated effect value (p = 0.025) is 0.004 (0.001, 0.007).
conclusionsWe identified two pathways by which ICTs can impact asthma through PMs, which might help in identifying potential targets for personalized treatment approaches.
