SpA-like changes in the spine CR in patients with DDD, DISH, and axSpA. The presence of SpA changes was defined by a positive score for erosions, sclerosis, squaring, syndesmophytes, or bridging syndesmophytes; the presence of degenerative changes was defined by the presence of spondylophytes or bridging spondylophytes. axSpA: axial Spondyloarthritis, CR: Conventional radiography, DDD: Degenerative Disc Disease, DISH: Diffuse Idiopathic Skeletal Hyperostosis, SpA: Spondyloarthritis. *Statistically significant difference (higher prevalence of SpA-like changes): DDD vs. DISH in cervical, DISH vs. DDD in thoracic, axSpA vs. DISH and DDD in lumbar spine
