Diagnosed with axSpA
ASAS=Assessment of SpondyloArthritis international Society; axSpA=axial spondyloarthritis; BASDAI=Bath Ankylosing Spondylitis Disease Activity Index; CRP=C- reactive protein; DMARD= disease-modifying antirheumatic drug; ESR=erythrocyte sedimentation rate; IBD=inflammatory bowel disease; NSAID=nonsteroidal anti- inflammatory drug; mNY=modified New York.
Missing values were below 5% except for axSpA diagnosis (5.6%), SJC, 5.7%,CRP, 7.1%,mNY criteria (17.3%), BASDAI, 15.0% and the number of patients still diagnosed as axSpA after one year of follow-up (58.9%).
