Comparison of indicators among groups. A–H The levels of WBC, NLR, PTC, CRP, nCD64 index, and T lymphocyte subsets (including CD3 + T cell, CD4 + T cell, and CD8 + T cell) among groups. Mixed Bloodstream Infection Subgroup has significantly higher nCD64 index and NLR levels, whereas it has significantly lower counts of CD3 + T cells, CD4 + T cells, and CD8 + T cells. WBC white blood cell count; NLR neutrophil to lymphocyte ratio, PCT procalcitonin, CRP C-reactive protein, nCD64 index  neutrophil CD64 index. Data in A–H were analyzed by independent Student’s t-test or Mann-Whitney U test
