Analysis of CSF samples and protein identification. Principal component analysis (PCA) showed the variability of CSF samples between and within groups in the neurology panel (A) and inflammation panel (B), respectively. Each point represents a sample, blue represents the control group, and green represents the SAH group. The closer the samples are, the more similar the expression patterns of the samples are; the farther the samples are, the more different the expression patterns of the samples are. The bar charts displayed the number of proteins identified in different CSF samples in different panels (C and D). Blue represents the control group and red represents the SAH group, n = 6
