  1. aACW = anterior chest wall; AS = ankylosing spondylitis; BME = bone marrow edema; MASES = Maastricht Ankylosing Spondylitis Enthesitis Score [16]; nrSpA = nonradiographic spondyloarthritis; SpA = spondyloarthritis. bACW tenderness in at least one of four MASES points (physician assessment); ACW pain indicated by patients on a manikin form (patient assessment). cMRI-detected lesion recorded in at least one of eight ACW joint locations by each of the seven readers. dMedian Cohen's κ values [range] of all seven individual readers.
