Performance of standardized patient reported outcomes developed for spondyloarthritis in primary and concomitant forms of fibromyalgia

Arthritis Res TherPublished Prospective cohort study

Authors' conclusion

ASDAS-CRP and duration of lumbar morning stiffness were not affected by cFM. FM-specific questionnaires also showed high scores in patients with SpA with cFM but not in those without.
