a Absolute cell counts and b percentages of CD3+ T cells, CD4+ T cells, CD8+ T cells, B cells, and NK cells in the mild (n = 18) and severe (n = 9) group were analyzed by flow cytometry. Shaded region showing the normal range of indicated cell subset. Colored symbols indicated deceased cases. Data are expressed as mean ± SD. *p < 0.05 by two-tailed Mann–Whitney U-test for a (p = 0.0124, p = 0.0354, p = 0.0199, and p = 0.0354, respectively) and b (p = 0.015).
