Correlation between lymphocyte subpopulation absolute counts and inflammation markers. Absolute counts of total T-lymphocytes and related subsets (CD3 + CD4+, CD3 + CD8+, CD3 + CD4 + CD8 + DP, CD3 + CD4 − CD8 − DN), B-lymphocytes and NK-cells (CD16 + CD56+) were correlated with IL-6 (column A), CRP serum concentrations (column B) and d-dimer plasma concentration (column C). Correlation was assessed with the Spearman’s test; Spearman r (only if statistically significant) and p are reported in the boxes; a two-sided p value of < 0.05 was considered statistically significant. ns not statistically significant, IL-6 interleukin-6, CRP C-reactive protein.
