The assessment of axial SpondyloArthritis (axSpA) lesions is important; not only to evaluate a major contributor to disease severity, but also to determine whether drugs are effective in inhibiting structural progression. In trials, assessment of axSpA lesions can be done locally in a study centre, or in a centralised manner by specifically trained readers. The potential impact of choosing one method rather than the other is unknown. In earlier work, we found the same—moderate—level of agreement between local reading (LocR) and central reading (CentR) as between the two central readers regarding radiographic sacroiliitis assessment.1 However, differences between LocR and CentR resulted in misclassification of some patients (ankylosing spondylitis (AS) or axSpA meeting Assessment of SpondyloArthritis international Society (ASAS) criteria).2 The modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) is the recommended tool to assess erosions, sclerosis, squaring and (bridging) syndesmophytes at each anterior vertebral corner of the cervical and lumbar spine.3 ,4 The objective of this study was to assess the agreement between baseline mSASSS values of patients with recent-onset inflammatory back pain (devenir des spondyloarthrites indifférenciées récentes (DESIR) …
