CSF sAPPα/ß in ALS and controls.

<p>Box and dot plots show (A) CSF sAPPα and (B) CSF sAPPß in ALS, Parkinson's disease (PD), and controls (CTRL) as well as (C) ratio CSF NfH^SMI35/CSF sAPPα and (D) ratio CSF NfH^SMI35/CSF sAPPß (right side). ALS fast = patients with rapid progression of disease over follow-up of 6 months, ALS slow = patients with slow progression of disease over follow-up. The box represents the 25^th to 75^th quartile, the whiskers represent the range, and the horizontal line in the box represents the median.
