Figure 2From: Discriminant validity, responsiveness and reliability of the arthritis-specific Work Productivity Survey assessing workplace and household productivity within and outside the home in patients with axial spondyloarthritis, including nonradiographic axial spondyloarthritis and ankylosing spondylitisMean changes from baseline in Work Productivity Survey by SpondyloArthritis International Society 20% improvement criteria clinical response at week 12. Change from baseline in Work Productivity Survey (WPS) by Assessment of Ankylosing Spondyloarthritis International Society 20% improvement criteria (ASAS20) clinical response at week 12 in overall axial spondyloarthritis (axSpA) population (randomized set, observed cases). *P ≤ 0.05, **P ≤ 0.01, #P ≤ 0.001; responders versus nonresponders. P-values were obtained using the nonparametric bootstrap-t method. Rate of interference is a score on a scale of 0 to 10 points (0 = no interference and 10 = complete interference).
