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

Purpose: Our objective was to explore the shared genetic risks between iridocyclitis and extraocular autoimmune diseases, as well as refine the regulatory network of genetic and environmental mechanisms by incorporating endocrine-disrupting chemicals (EDCs). Methods: Using summary statistics reporting genome-wide association study findings within European ancestry, we first investigated the genetic associations between iridocyclitis and extraocular autoimmune diseases. We then performed causal inference using Mendelian randomization (MR). By integrating genetic and causal associations, we explored the comorbid genetic structure and shared risk genes between iridocyclitis and ulcerative colitis (UC) through cross-trait analysis and a transcriptome-wide association study (TWAS). Finally, we constructed an interaction network between EDCs and shared risk genes by combining chemical-genetic interaction data. Results: Linkage disequilibrium score regression identified significant positive genetic correlations between iridocyclitis and psoriasis (rg = 0.219, P = 3.15e-03) and ulcerative colitis (rg = 0.248, P = 9.21e-04). Local genetic correlation analysis revealed genetic overlap on chromosomes 1 and 6. No significant genetic association was found between iridocyclitis and seven other autoimmune diseases. MR identified bidirectional causality only between UC and iridocyclitis. Genetic analysis identified 11 independent shared single-nucleotide polymorphisms between UC and iridocyclitis, and colocalization analysis identified a shared causal variant (rs17369215). Subsequent TWAS identified three shared risk genes for UC and iridocyclitis, and an interaction network involving 25 EDCs and shared risk genes was constructed based on chemical-genetic interaction data. Conclusions: This study identified the shared genetic structure and key genes between iridocyclitis and UC, highlighting the significant role of EDCs through gene-environment interactions in the comorbidity of iridocyclitis and UC. Translational Relevance: This study reveals a common genetic association between iridocyclitis and extraocular autoimmune diseases.
