Spondyloarthritis & psoriatic arthritis

Variability of Psoriatic Arthritis Impact of Disease questionnaire (PsAID12) thresholds in psoriatic arthritis: data from the ReFlaP study

Rheumatology (Oxford)Published Cross-sectional study

Authors' conclusion

This study established cutoffs for PsAID12 in a clinical practice observational population, corresponding to remission and varying levels of disease impact.
