Fig. 2. Intra-individual change in CSF Aβ 42 as a function of age.

Fig. 2

Multi-run (A) and single-run INNOTEST Aβ42 values (B) are plotted as a function of age at time of CSF collection. Each point represents one CSF sample, and samples from a single individual are connected with a line. The overall group change in Aβ42 as a function of age (m) was calculated using linear mixed models and is represented by a dashed red line.
