Proportions of naive and CD31+ CD8+ T cells. YAT patients showed lower proportions of naive CD8+ T cells than YHC (a). YATEC patients demonstrated lower proportions of CD31 + CD8+ T cells than YHC. Lowest naive and CD31+ CD8+ T cells were found in OHC compared to YHC (b). Bars represent mean percentages ± standard deviation, numbers (n) of investigated individuals for each group. A p ≤ 0.05 indicates statistical significance (Mann–Whitney U test). YHC showed a negative correlation of CD31+ naive CD8+ T cells with chronological age (d), whereas YATEC did not (c). In YATEC patients, CD31+ naive CD8 + T cells negatively correlated with age at thymectomy (e). Spearman’s Rank correlation coefficient, R; p ≤ 0.05 indicates statistical significance
