The correlations of cytokine concentrations in serum with pleocytosis. The correlation of the concentrations of CXCL2 (a–c) and IL-17F (d–f) in serum (expressed in pg/ml) of TBE patients on admission to hospital, presented on horizontal axes, with the cerebrospinal fluid total pleocytosis (a, d), lymphocyte count (b, e), and neutrophil count (c, f) (in cells/μl) on vertical axes. The data from the individual patients are shown with points, the linear fit with a continuous line and the 95% confidence interval with dashed lines. The strength R and statistical significance p of the correlations are shown directly on plots. NS non-significant
