The extent of skin involvement of systemic sclerosis was determined by modified Rodnan scores. Broken line indicates cutoff value for patients with severe skin involvement (Rodnan score ≥20). Bars represent the mean ± standard error of the mean of MMP-9 in patients with severe versus mild-to-moderate skin involvement (Rodnan score
