Quantitative analysis and clinical relevance of potential biomarkers. A–C The specific protein levels were measured in CSF samples via ELISA kits. The concentration (Y-axis) was normalized to the total protein in CSF. Generally, data that passed the normality test were described by the mean with SD and compared by unpaired t test. *p < 0.05, “ns” refers to p > 0.05. D, E Simple linear regression was used to assess the correlation between clinical factors and proteins levels. Solid lines are the fit of linear regression, and dotted lines represent the 95% confidence interval. F ROC analysis of multiple variables. The diagonal dashed line reflects a random prediction (AUC = 0.5)
