Survival curves of patients with systemic sclerosis with and without myopathy: Disease duration is the number of years since the first non-Raynaud phenomenon. SSc patients with myopathy had lower survival rates. Kaplan–Meier analysis revealed that the 3-year, 5-year, and 10-year survival rates for SSc patients with myopathy were 97.7%, 95.1%, and 81.4% respectively, compared with those of patients without myopathy, which were 98.8%, 97.8%, and 94.1%, respectively, (P = .028)(the black arrow).
