Among 168 patients who were determined to have axial spondyloarthritis (axSpA) according to the clinical arm of the ASAS classification criteria, response to TNF inhibitor therapy was dependent on the presence or absence of objective signs of axSpA (such as arthritis, dactylitis, enthesitis, uveitis and others). Only 13.7% of patients with non-radiographic SpA and no objective signs achieved a 50% improvement in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI 50) at 3 months, compared with 45.1% of the group of patients with one or more objective signs.
