LEDD is L-dopa equivalent daily dosage, UPDRS is Unified Parkinson’s Disease Rating Scale, MoCA is Montreal Cognitive Assessment, H&Y is Hoehn & Yahr scale, NA is not applicable; Values reported are group median (interquartile range). ^aDetermined by comparing LRRK2+/PD- to LRRK2+/PD+ using the Dunn post hoc test following Kruskal-Wallis test of all groups. ns is not significant as determined by Pearson chi square (gender), ANOVA (age at test), t test (age at onset), Mann-Whitney test (LEDD) and Kruskal-Wallis test (H&Y, UPDRS III)
