Comparison of CSF proteins between Parkinson’s disease (PD), atypical Parkinsonian disorders (APD) and Controls. a Boxplots of the most significantly changed proteins, adjusted for age and sex. Levels are normalised protein expression (NPX). T-test for groupwise comparisons. b Validation of Midkine (MK) levels using a commercial ELISA assay (upper) and comparison with Olink NPX values by a linear model regression (middle) and z-scored boxplot comparisons (bottom)
