FIGURE 1

Correlation between plasma and CSF Aβ40, Aβ42, Aβ42/Aβ40. No correlation was detected between Aβ IP eluates from plasma and CSF. Note the weak correlation (r = 0.169, p = 0.000988) between IP eluates and CSF Aβ42, and a stronger correlation (r = 0.47, p = 2.76e‐22) between plasma and CSF Aβ42/Aβ40. Aβ40, amyloid beta X‐40; Aβ42, amyloid beta X‐42; Aβ42/Aβ40, amyloid beta X‐42/amyloid beta X‐40 ratio; CSF, cerebrospinal fluid; IP, immunoprecipitation. The Pearson´s correlation coefficient (r) and the corresponding p‐values are indicated in each figure part. In addition, a Deming regression is shown in each figure part.
