Variables of the MCA—contribution to the first 2 dimensions and correlation. Contribution of variables (expressed in %) to the first (A) and second (B) dimension of the MCA. The dotted red line denotes the average value expected if all variables contributed equally to the dimensions. Presence or absence of a variable is denoted by 1 or 0 after the name, except for the CSF white cell count where 0, 1 and 2 denote ≤ 4, 5–200 and > 200 cells/ul, respectively. Dimension 1 is related to the initial clinical presentation, dimension 2 is related to laboratory measurements (see text for details). On the correlation plot of the variables (C), variable contribution to the dimensions of the MCA is indicated in color and distance is inversely proportional to the correlation between variables. Variable abbreviations: "poor-mRS-enrol": poor mRS score at enrolment, "im-comp": immunocompromised, "hiv": HIV-status, "alt-ment": altered mental status, "comat": comatose, "neck-stf": neck stiffness, "fac-neur-signs": facial focal neurological signs, "musc-weak": muscle weakness, "abn-mvt": abnormal movements, "csf-abn-prot": abnormal level of protein in the CSF, "csf/bld-glc" low CSF to blood glucose ratio, "csf-wc-hi": elevated CSF white cell count, "csf-%ntr-hi": elevated percentage of neutrophils in the CSF, "gend-f": female gender, "wbc-hi": elevated white blood cells, "low-sod": low sodium, "csf-press-hi": elevated opening pressure, "age > 65": age over 65.
