The convalescent cerebrospinal fluid parameters stratified by clinical outcome. The comparison of the cerebrospinal fluid (CSF) parameters in the control examination 10–16 days after the hospital admission between the groups of patients with full recovery (I, n = 121), patients with subjective complaints on follow-up (II, n = 38), and patients with long-lasting neurologic deficits (III, n = 7). The data from individual patients are shown with circles, median values with horizontal lines. Some individual data points in some plots may be lacking because of incomplete data. *A statistically significant trend with non-parametric ANOVA, p < 0.05. **The same with p < 0.01. ^#A trend with a statistical significance at p = 0.056. a CSF total pleocytosis (cells/μl). b CSF lymphocyte count (cells/μl). c CSF neutrophil count (cells/μl). d CSF protein concentration (mg/dl). e CSF albumin concentration (mg/dl)
