Ankylosing spondylitis and the genetic correlation of extra-articular manifestations: Evidence from bidirectional Mendelian randomization and Bayesian colocalization.
Article in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Spondyloarthritis (SpA) encompasses a group of inflammatory joint disorders affecting the spine and joints, including ankylosing spondylitis and nonradiographic axial SpA, exhibiting diverse extra-articular manifestations. Genetic factors, beyond human leukocyte antigen B27, play a significant role in SpA development. Leveraging advanced statistical methods, this study explores bidirectional Mendelian randomization (MR) and Bayesian colocalization to unravel the genetic links between SpA and its extra-articular manifestations. Positive MR analysis indicates causal relationships between ankylosing spondylitis and various extra-articular conditions. Leave-one-out analysis suggests that these effects are not driven by individual single-nucleotide polymorphisms. In reverse MR, potential reverse causal relationships are explored, revealing uveitis, inflammatory bowel disease, and ulcerative colitis as candidates. Colocalization analysis, unfortunately, does not identify shared genetic foundations. In conclusion, seronegative spinal arthritis may lead to myocarditis, atrioventricular block, bronchiectasis, Crohn disease, and coccygeal plexus syndrome, while there is a 2-way causal relationship with uveitis, inflammatory bowel disease, and ulcerative colitis.
