Older patients showed significantly higher enthesitis, bone erosion, and NBF scores. Multivariable analysis revealed that age \u2265 60 years was linked to significantly higher inflammatory and structural enthesitis (adjusted \u03b2 6.37 and 14.6, respectively), bone erosion (\u03b2 2.53), and NBF (\u03b2 13.7) scores, and that b\/tsDMARD exposure correlated with significantly higher synovitis (\u03b2 12.8) and tenosynovitis scores (\u03b2 5.95).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Older age correlated with more severe inflammatory and structural lesions, reflecting either a more severe PsA phenotype or overlap with age-related changes.
