Table 4 Correlation analyses of gagCEST values of lumbar IVDs and serological (CRP level), clinical/functional (BASDAI and BASFI), and imaging scores. p values < 0.05 were considered significant and are given in bold. Please refer to Table 3 for an explanation of the abbreviations

From: Functional MR imaging beyond structure and inflammation—radiographic axial spondyloarthritis is associated with proteoglycan depletion of the lumbar spine
