PsA patients in the SIRENA registry were classified according to ASAS criteria and were DMARD-naïve for SpA at baseline. Of 203 PsA patients, 100 were prescribed csDMARDs, 50 bDMARDs, and 27 other systemic treatments, mostly NSAIDs. Treatment could be switched during the observation period. The 6-month predictors of MDA presented here were identified through univariate analyses. In multivariate analyses, no factors were identified as significant predictors of MDA at 6 months.1
