Differential expression of bone metabolism biomarkers in various types of arthritis and their diagnostic performance: a cross-sectional study.
Article in BMC musculoskeletal disorders, 2026. 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
backgroundBone metabolism markers have shown significant potential for diagnosis and prognosis in arthritis. This study aims to evaluate expression levels of bone metabolism markers in various types of arthritis and their diagnostic value.
methodsThis study included 1,838 participants, comprising 919 arthritis patients (Rheumatoid Arthritis (RA), Systemic Osteoarthritis (SO), Gouty Arthritis (GA), and Ankylosing Spondylitis (AS)) and 919 healthy controls, treated at our hospital from July 2019 to February 2022. Data were collected on demographics, bone metabolism markers and inflammatory markers. Correlation analysis was performed between inflammatory factors and bone metabolism markers. ROC curve analysis was conducted to assess the diagnostic performance of these markers.
resultsThere was no significant demographic difference. All inflammatory markers were elevated in the arthritis group (P < 0.001). Bone formation markers (N-MID, Total-P1NP, OC, BSAP) were lower, and bone resorption markers (β-CrossLaps, CTX-I) were higher in the arthritis group (P < 0.001). Significant correlations were found between inflammatory and bone metabolism markers (P < 0.01). ROC analysis showed OC had the highest diagnostic accuracy in SO (AUC = 0.948), BSAP in GA (AUC = 0.803), and RA (AUC = 0.906), and OC in AS (AUC = 0.747).
conclusionThis study highlights the diagnostic value of bone metabolism markers in distinguishing arthritis subtypes, revealing their correlation with inflammatory markers.
