Fig. 4: Correlations with clinical parameter, UPDRS-III.

a Pearson correlation scores and associated FDR-values [−log10] of all protein intensities with the UPDRS-III scores; 20 LRRK2 PD and 21 HC were included. Significantly correlated proteins with an FDR of 5% after Benjamini–Hochberg correction are labeled. b The scatterplots of three biomarkers with strong Pearson correlation scores (>0.7).
