Suzuki T, Iwamoto N, Yamasaki S, Nishino A, Nakashima Y, Horai Y, et al. Upregulation of thrombospondin 1 expression in synovial tissues and plasma of rheumatoid arthritis: role of transforming growth factor-β1 toward fibroblast-like synovial cells. J Rheumatol 2015;42:943–7.
In Figure 3, panel B, the unit of measurement was incorrect. The corrected figure is reprinted below. In addition, in the second paragraph of the Results section, the representative results for thrombospondin 1 associated with circulating immune complexes in the culture supernatants of each stimulated fibroblast-like synovial cell should be in ng/ml. In the fourth paragraph, the unit for transforming growth factor-β1 at baseline and after induction of new treatment should be ng/ml.
