 For ACB scale, adjusted R² = 0.364, ANOVA p < 0.005, F = 7.516; for ARS scale, adjusted R² = 0.417, ANOVA p < 0.001, F = 14.6; for ADS scale, adjusted R² = 0.170, ANOVA p = 0.004, F=4.90. ACB, Anticholinergic Cognitive Burden scale; ADS, Anticholinergic Drug Scale; ARS, Anticholinergic Risk Scale; LEDD, levodopa equivalent dose; AP, antiparkinson.
