    The Uric Acid-Inflammation-Metabolism (UIM) score effectively predicts osteoarthritis (OA) risk by integrating uric acid metabolism, inflammation, and metabolic disturbance.

  • 2

    Participants in the highest UIM score quartile had a 2.63-fold increased risk of OA compared to those in the lowest quartile, indicating significant risk stratification.

  • 3

    The UIM score demonstrated good discrimination (AUC = 0.707) and outperformed individual biomarkers and traditional models in predicting OA risk.

  • 4

    The uric acid dimension contributed the most to the UIM score, highlighting its primary role in OA pathogenesis compared to inflammation and metabolic factors.

  • 5

    The UIM score's robustness and generalizability were confirmed through external validation, making it a practical tool for OA prevalence assessment.
