UPDRS = Unified Parkinson’s Disease Rating Scale, Working mem = working-memory score, Proc speed = processing-speed composite score, Mem comp = memory composite score, and clustering = clustering coefficient score. Partial correlation controlled for age using Spearman’s method transformed to Fisher’s z-scores using the “psych” package in R. Black bins correspond to |z| > 0.55 and correlated results. * corresponds to statistically significant difference to controls; # corresponds to statistically significant difference to PD-Well, calculated from r values with http://vassarstats.net/rdiff.html.
