The proportion of CD4+Th17 cells in Tcc group was significantly higher than that in the HT group (31.44 ± 0.9579) vs. (21.56 ± 1.831) (p < 0.05), and the proportion of CD4+Th17 cells in the Tcc + ETO group was significantly lower than that in the Tcc group (14.96 ± 2.363) vs. (31.44 ± 0.9579) (p < 0.05) (Fig. 2E). Here, CD4 is linked to hematocrit.
