Figure 1. Venn diagram showing the amount of overlap of our dataset with a comparable dataset of proteins detected in the CSF of “normal clinical value” or “neurologic surrogate-normal” individuals who required a lumbar puncture for clinical reasons as reported by Zougman et al[8].

The large circle represents the 2630 proteins observed in our comprehensive dataset of proteins detected in the CSF of normal individuals. The small circle represents the 798 proteins identified in the analysis by Zougman et al.
