Violin plots visualizing the distribution of data for six parameters of interest for patients classified as SI and VI. Box plot overlays to improve visualization of the means and outliers. Some variables were log transformed due to outliers to improve visualization where indicated. The asterisks show significance levels for the Wilcoxon rank sum test between NI vs SI and VI (NI vs AB in Table 3), and SI vs VI, respectively. * indicate \(p < 0.05\). ** indicate \(p < 0.01\). CSF is cerebrospinal fluid. The glucose ratio is the ratio of CSF glucose to blood glucose. The GE ratio is the ratio of granulocytes to erythrocytes in CSF. The GM ratio is the ratio of granulocytes to monocytes in CSF
