Baseline assessments included disease activity (European League Against Rheumatism (EULAR), Sj\u00f6gren\u2019s Syndrome Disease Activity Index (ESSDAI)), patient-reported symptoms (EULAR Sj\u00f6gren\u2019s Syndrome Patient Reported Index (ESSPRI)), C reactive protein (CRP), Schirmer\u2019s test (ST) and autoantibody status. Irreversible damage was evaluated using the Sj\u00f6gren\u2019s Syndrome Damage Index (SSDI) across ocular, oral and systemic domains. Predictors of damage accrual were analysed using Cox proportional hazards models and Kaplan-Meier curves. Exploratory Least Absolute Shrinkage and Selection Operator (LASSO) and principal component analysis (PCA) analyses assessed domain-specific contributions and relationships between subjective and objective measures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At baseline, 48% of patients had SSDI\u22651: ocular 25.4%, systemic 22.5% and oral 14.3%. After 5 years, 65% had cumulative damage: ocular 34.2%, oral 21.7% and systemic 40.8%. Higher baseline ESSDAI predicted damage across all domains. Elevated ESSPRI was associated with oral damage, while abnormal ST strongly predicted ocular damage. Anti-Ro\/La antibodies, elevated CRP and recurrent oral infections were linked to higher domain-specific damage. LASSO analyses showed glandular, peripheral nervous system and pulmonary ESSDAI domains independently contributed to systemic damage. PCA confirmed that patient-reported symptoms and systemic activity represent complementary, independent dimensions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Irreversible damage in SD occurs early, often present at diagnosis and affects multiple organ domains.
