Identification of overlapping genetic loci between inflammatory bowel disease and major depressive disorder.
Article in European archives of psychiatry and clinical neuroscience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPatients diagnosed with inflammatory bowel disease (IBD) are often observed to suffer from co-occurring major depressive disorder (MDD). Although the precise mechanisms remain elusive, there is a possibility of a genetic overlap between these conditions.
methodsGenome-wide association study data collected from two IBD cohorts alongside one MDD cohort were analyzed. Initially, linkage disequilibrium score regression, genetic covariance analysis, and high-definition likelihood estimation was applied to explore the overall correlation between the diseases. Local genetic correlations were subsequently assessed through heritability estimation derived from summary statistics. Following this, genetic overlap analysis was conducted based on the conditional/conjunctional false discovery rate (cond/conjFDR) statistical model, identifying shared genetic genes across various traits.
resultsOn a genome-wide scale, significant correlations, both overall and local, were observed between IBD (including Crohn’s disease and ulcerative colitis) and MDD. Genetic overlap between the two disorders was confirmed through conjFDR analysis, which also pinpointed relevant genetic risk genes. Ten specific genes, namely RBMS1, C3orf84, AC008703.1, ZNF365, MED24, TCF4, CRB1, CCSER1, P4HA2, and RASGRP1, emerged as noteworthy. Additionally, these genes exhibited enrichment in pathways related to synaptic transmission.
conclusionThis investigation presents genetic evidence supporting the comorbidity of IBD and MDD, thereby contributing to a deeper understanding of the pathophysiological connections between these conditions.
