Figure 2 Association between demographic, etiological, clinical factors, laboratory results, treatment, and unfavorable outcome (death). CI – confidence interval, WBC – white blood cells. Certain nominal variables, such as N. meningitidis as an etiological agent, the need for intensive care, and limb paresis, were excluded from the graph as the odds ratio for unfavorable outcome could not be computed. Arrows indicate high values of the upper 95% confidence interval that could not be visualized in the graph. (Microsoft Excel, version 16.74, Microsoft).
