Figure 7From: Follistatin-like protein 1 is elevated in systemic autoimmune diseases and correlated with disease activity in patients with rheumatoid arthritisSerum levels of FSTL1 in RA patients before and after treatment. Paired serum samples were obtained from the 20 patients before treatment and after 6 months of treatment with DMARDs and/or infliximab. (A) Fifteen patients achieved at least an ACR20 response. (B) Five nonresponders did not achieve an ACR20 response. Each point represents an individual value. FSTL1, follistatin-like protein 1; RA, rheumatoid arthritis; DMARDs, disease-modifying antirheumatic drugs; ACR20, improvement of ≥20% according to the American College of Rheumatology (ACR) response criteria.Back to article page
