Correlation between cytokines and lymphocyte subsets on admission and days from hospital admission to death in the fatal patients. a Correlation between the levels of IL-2R, IL-6, IL-8, and TNF-α and days from admission onset to death (n = 51). b Correlation between the numbers of B cells, CD4⁺ T cells, CD8⁺ T cells, and NK cells and days from admission onset to death (n = 51). Each symbol represents an individual fatal patient. *Days from admission onset to death. IL-2, interleukin-2 receptor; IL-6, interleukin-6; IL-8, interleukin-8; TNF-α, tumor necrosis factor-α
