Confounding Factors Influencing Amyloid Beta Concentration in Cerebrospinal Fluid

Figure 4

(a) Boxplot (whiskers represent minutes and max values) of CSF A𝛽₄₂ concentrations using different assays. For each kit the CSF was analyzed twice, neat and threefold diluted in a detergent-containing buffer. Each box represents 40 samples (20 AD + 20 controls). (b) Area under ROC curve for different assays with whiskers representing a 95% confidence interval. Neat, and threefold diluted CSF are represented by white and dark boxes/bars, respectively.
