The Relationship between Different Assays for Detection and Quantification of Amyloid Beta 42 in Human Cerebrospinal Fluid
Figure 1
(a) CSF Aβ 42 levels measured in both ELISA and ECL assay. Box plots of CSF Aβ 42 levels from ELISA and ECL separated by diagnosis (AD and AMC) and method of detection. Boxes represent the interquartile ranges: bottom of box, black dot, and top of box indicate the 25, 50, and 75th percentile of the data. The whiskers (dashed bars) extend to the most extreme data points, which are no more than 1.5 times the height of the box away from the top or bottom of the box. (b) Correlation between ELISA and ECL. Correlation coefficients .
