remarkably lower (4.5%) than in those who did not fulfil ASAS and ESSG-criteria (46%) or ASAS and Amor-criteria (41%). Additionally, CRP values were higher in the group of patients who did not fulfil any of the criteria compared with those who fulfilled all criteria.
The overlap in criteria fulfillment (figure-1) was presented using a Venn-diagram representing the numbers of patients with any clinical diagnosis of SpA fulfilling each criteria set. A substantial percentage of patients (42%, n=244) met ASAS and ESSG as well Amor-criteria. In contrast, relevant numbers of patients with a clinical diagnosis of SpA fulfilled one classification criteria set exclusively: Only ASAS-axSpA: 49 patients; only ASAS-pSpA: 33 patients; only ESSG: 25 patients; and only Amor- criteria: 5 patients.
