Fig. 4From: CSF protein ratios with enhanced potential to reflect Alzheimer’s disease pathology and neurodegenerationProtein ratio and individual protein CSF level distribution in individuals stratified based on AT status and diagnosis. A GAP43/PTPRN2 and SNCB/GAP43 distribution in the discovery cohort, B GAP43, SNCB and PTPRN2 levels in the discovery cohort. Distributions between the individual groups are compared using the Wilcoxon rank-sum test and the resulting p-values are reported in the individual plotsBack to article page
