Autoantibodies in cGVHD. Autoimmune autoantibodies such as ANA (A), anti-dsDNA antibody (B), anticardiolipin antibody (C), and antimitochondrial antibody (D) were measured by ELISA, and patients with early onset (3-8 months) cGVHD (▴) were compared with 6-month controls (■); patients with late onset (≥ 9 months) cGVHD (♦) were compared with 12-month controls (▾). Bars indicate mean values for each group. ***P < .001. NS indicates not significant.
