VP1 assessment in GD samples and controls. We confirmed the presence of VP1 in GD samples. A, Number of VP1+ thyrocytes in the GD subgroups and controls. There were significantly more VP1+ thyrocytes both in the chronic GD group and the new GD group compared to controls. The chronic GD group had significantly more VP1+ thyrocytes than the new GD group. Bars represent median and interquartile range. B, Proportion of double-positive samples (VP1+/HLA I+) in the GD group and the controls. We found significantly more double-positive samples in the GD group than in the control group. *P less than or equal to .05; **P less than or equal to .01; ***P less than or equal to .001. GD, Graves disease; HLA, human leukocyte antigen; VP1, enteroviral capsid protein 1.
