The relationship between PHA spot number and lymphocyte non-specific function. (A) Correlation between PHA spot number and non-specific function of CD4+ T cells, CD8+ T cells, and NK cells in 208 participants. Each symbol represents an individual donor. (B) Scatter plots showing the results of CD4+ T cell non-specific function, CD8+ T cell non-specific function, and NK cell non-specific function under different PHA spot number. Horizontal lines indicate the median. *P < 0.05; **P < 0.01; ***P < 0.001; ns, no significance (Mann-Whitney U test). (C) Flow plots showing the representative results of CD4+ T cell non-specific function, CD8+ T cell non-specific function, and NK cell non-specific function under different PHA spot number. PHA, phytohemagglutinin.
