PD-1 expression in the HBV-specific CD8+ T cells. a Percentage of PD-1+ cells in total CD8+ T cells (CD8 + PD-1+/CD8+) determined by flow cytometry. Data are shown as median (IQR). IQR = interquartile range. P > 0.05, by Kruskal-Wallis H test. b Percentage of PD-1+ cells in the HBV-specific CD8+ T cell population (pentamer + CD8 + PD-1+/pentamer + CD8+) determined by flow cytometry. Data are shown as median (IQR). IQR = interquartile range. ns represent no significant, **represent P < 0.01, ***represent P < 0.001, by Mann Whitney test. c Representative flow cytometry data of PD-1 expression
