Figure 2. Number of patients meeting the ASAS classification criteria according to clinical diagnosis made by rheumatologist.

ASAS, Assessment of Spondyloarthritis international Society; AS, ankylosing spondylitis; uSpA, undifferentiated SpA; ReA, reactive arthritis; PsA, psoriatic arthritis; IBD, SpA associated with inflammatory bowel disease.
Figure-3 and Table-3 describe criteria overlap in two manners: Table-3 describes the concordance rates between ASAS, ESSG and Amor, as well as these rates with MRI-modified ESSG and Amor- criteria. Concordance between ASAS and ESSG is approximately 70% and between ASAS and Amor approximately 60%. Of note, the concordance rates did not increase significantly by substituting the radiologic criterion by the MRI criterion. Figure-3 starts with a clinical diagnosis of SpA. The large majority of patients with a clinical diagnosis fulfill any of the existing criteria, but there is marked heterogeneity in doing so: all combinations of criteria can be found, and there is only a small fraction of patients that classifies consistently negative.
