Differences in bone microarchitecture in patients with nonradiographic axial spondyloarthritis (nr-axSpA). a Changes of total, cortical, and trabecular bone mineral density (BMD) and bone microarchitecture reflected by total bone volume (BV/TV) and cortical thickness (Ct.Th) between patients with axial spondyloarthritis (SpA) and healthy control subjects. b Changes of total, cortical, and trabecular BMD and bone microarchitecture reflected by BV/TV and Ct.Th between patients with nr-axSpA with or without a history of treatment with > 5 mg prednisolone equivalent for more than 3 months. GC Glucocorticoids, N.S. Not significant, HA Hydroxyapatite. *p < 0.05
