Correlation of biomarkers with Parkinson’s disease (PD) progression. a. Correlation between MCP-1 and Hoehn and Yahr (HY) progression score; b. Correlation between MMP-10 and unified Parkinson’s Disease rating scale (UPDRS) progression score. Data were analyzed using Spearman correlation. Biomarker values are expressed as normalized protein expression. Right whisker plots represent median, interquartile range, minimum, maximum and outliers of disease score progression. Upper whisker plots represent median, interquartile range, minimum, maximum and outliers of the protein marker levels in cerebrospinal fluid of PD patients. Rho was > 0.600 and p value < 0.01 for both correlations
