Comparison of Flanker Task performance according to GBA1 and DBS status. In persons with Parkinson's disease (PwP), Flanker scores were significantly different between GBA1+DBS+ (red) vs. GBA1−DBS− (white) groups (P = 0.041). Flanker scores were also significantly different between GBA1+DBS+ (red) vs. GBA1−DBS+ (teal) groups (P = 0.010). After adjustment for covariates, group differences in Flanker scores remained significant when comparing GBA1+DBS+ vs. GBA1−DBS+ PwP only (P = 0.030).
