Clinical, laboratory, radiological and treatment data were collected and compared with baseline. Diagnostic changes according to the rheumatologist\u2019s judgement and their associated factors were analysed using multivariable logistic regression.

Of these, 411 were physically re-evaluated, while 125 were confirmed deceased. Among the 411 patients, 31.6% experienced a change in diagnosis in the REGISPON-3 visit, mainly from undifferentiated SpA to axial SpA or psoriatic arthritis. In multivariable analysis, dactylitis, younger age and lower Bath Ankylosing Spondylitis Radiology Index scores were associated with diagnostic change. The use of biologic disease-modifying antirheumatic drugs (bDMARDs) increased from 13.1% to 52.1%. However, the median time to first bDMARD from symptom onset was 32 years (95% CI 30 to 35) and 28 years from diagnosis (95% CI 26 to 32). Among the 125 patients who died, the leading causes were infections (21.6%), cardiovascular (CV) events (20.0%) and cancer (19.2%).<\/jats:p>\n                  <\/jats:sec>\n
