Factor 1 and factor 4 derived from CSF gene expression discriminate patients grouped by cluster analysis. Scores for the four factors defined by factor analysis on CSF gene expression data are shown for each patient classified into clusters 1, 2, or 3 in cluster analysis. Statistically significant differences in factor scores between group 1 (n = 24) and group 2 (n = 6) patients were assessed by Mann-Whitney test; p values ≤0.0125 are shown, n.s. not significant. Each dot represents the score value for that specific factor in each individual patient; the line marks the median value
