Levels of circulating CD8⁺ T cells are decreased in AAD patients. Flow cytometry was used to calculate the frequencies of circulating CD8⁺ T cells in PBMC from AAD patients (n = 15) and healthy controls (n = 16). Non-parametric Mann–Whitney U test was used to test for statistical differences between patients and controls, (*P < 0.05). The bars display the mean for the whole group
