"If a specificity threshold for a given MRI lesion of at least 0.9 is applied for axial MRI to discriminate between axial SpA [spondyloarthritis] and background variation in healthy controls or in differential diagnostic conditions, no more than 10% of healthy controls in our study should meet this criterion by an individual level data
