Association of UCMA With Cartilage Pathogenesis and Inflammation in Patients With Rheumatoid Arthritis: A Novel Biomarker.
Article in Journal of clinical laboratory analysis, 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
backgroundRheumatoid arthritis (RA) is a persistent autoimmune disorder that impacts the joints, leading to a reduction in physical function and a decline in overall well-being. UCMA is a vitamin K-dependent protein that plays a role in some human diseases, including osteoarthritis and cardiovascular disorders. Nevertheless, the possible role of UCMA in the pathogenesis of RA remains unclear. Therefore, we aimed to investigate the expression of UCMA in serum samples of patients with RA, its relationship with disease activity and some blood markers.
methodsThe current study included 98 RA patients and 24 healthy individuals. Serum UCMA, COMP, TNF-α, and IL-6 levels were measured using enzyme-linked immunosorbent assay.
resultsSerum UCMA, COMP, TNF-α, and IL-6 expressions were significantly increased in RA patients compared to healthy controls (p < 0.05). The ROC curve analysis demonstrated that blood UCMA, COMP, TNF-α, and IL-6 levels had the capability to differentiate between patients with RA and healthy controls (p < 0.05). UCMA was positively correlated with certain laboratory indicators, such as COMP, TNF-α, IL-6, CRP, and CCP.
conclusionHere, we report for the first time that UCMA may reflect cartilage degeneration and inflammatory changes in RA patients. Furthermore, UCMA could be employed as a predictive or diagnostic marker in the clinical practice of RA.
