Patients were classified into radiographic axSpA (n\u2009=\u2009322) and non-radiographic axSpA (n\u2009=\u200966) groups according to the fulfilment of modified New York criteria by X-ray. Patient characteristics of the two groups were compared. Receiver operating characteristic (ROC) curve analysis was conducted to determine the cut-off values for age and symptom duration that best distinguish non-radiographic axSpA from radiographic axSpA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Compared with patients with radiographic axSpA, those with non-radiographic axSpA were younger at diagnosis (35.7\u2009\u00b1\u200911.3\u2009years versus 26.8\u2009\u00b1\u20097.8\u2009years, p\u2009&lt;\u20090.001) and had shorter symptom duration [5.1 (2.1\u201312.0) years versus 1.0 (0.5\u20133.2) years, p\u2009&lt;\u20090.001].
