Figure 2From: Construct validity and responsiveness of the simplified version of Ankylosing Spondylitis Disease Activity Score (SASDAS) for the evaluation of disease activity in axial spondyloarthritisScatter plots of the composite disease activity indices at baseline. All analyses indicate a highly significant degree (p < 0.0001) of correlation among the composite indices: (A) SASDAS versus ASDAS-ESR, (B) SASDAS versus ASDAS-CRP, (C) SASDAS versus BASDAI, (D) SASDAS versus BASFI, (E) SASDAS versus EQ-5D.Back to article page
