CRP and uveitis: Relatedly, while we systematically tested associations between all cell populations and multiple clinical covariates—including disease duration, treatment status (e.g., MTX, bDMARDs, steroid injection), and the presence of uveitis—we found no statistically significant associations apart from CRP levels, underscoring the need for validation in larger cohorts to better define the relationship between synovial cell composition and clinical phenotypes.
