1 · What the graph read from it

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.

2 · The registry

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

Objective: To systematically identify potential pathological molecular and therapeutic targets for type 2 airway inflammatory diseases using Mendelian randomization (MR) and co-localization analysis. Methods: This study analyzed 4,302 druggable plasma proteins as exposure factors and performed transcriptional MR analysis using their cis-expression quantitative trait loci (cis-eQTL) as instrumental variables. Disease outcome datasets from the UK Biobank and Finnish Cohortwere used for discovery and replication validation, respectively. For proteins successfully validated, cis-protein quantitative trait loci (cis-pQTL) were further used for protein-level MR analysis. By combining co-localization analysis, reverse MR analysis, and mediation analysis, we investigated the association of these plasma proteins with allergic rhinitis (AR), asthma (AS), and nasal polyps (NP). Results: cis-eQTL MR analysis of 2528 proteins identified 10 proteins associated with AR (TLR10, ERBB3, PNMT, etc.), 7 associated with AS (ERBB3, SLC40A1, PRKCQ, etc.), and 3 associated with NP (IL18RAP, AXL, ERBB3). cis-pQTL MR analysis showed that IL18RAP was associated with lower NP disease risk, while ERBB3 was associated with lower risks of AR, AS, and NP. Co-localization analysis supported the association between ERBB3 and AR (pp.H4 = 0.910). Mediation analysis revealed that the associations between ERBB3 and AR/AS were mediated by eosinophils, with mediation effects accounting for 12.51% and 17.64% of the observed associations, respectively. Conclusion: This study identified unique and shared molecular targets for type 2 airway inflammatory diseases, with ERBB3 potentially serving as a shared protective factor and biomarker for AR, AS, and NP.
