Conclusions While the frequency of clinical arthritis observed in patients with systemic sclerosis was 32.8%, the true overlap between of SSc and RA was 6.6% in this study. We also observed the frequency of positive anti-CCP in 20% of patients with arthritis versus no patients with SSc without arthritis.
