Registered outcomes1

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
Primary
The Investigators Will Assess Effect Size With Each Scale for Detecting Change From Baseline and Change Between Amantadine and Placebo; Allowing Assessment of Sensitivity and Specificity for Each Scale Based on Receiver Operator Characteristics (ROC).
18 months
Analyses of primary outcome measures tested sensitivity to change in dyskinesia (time effect) as well as sensitivity to differences in treatment effect (time-by-treatment interaction). These analyses were conducted using repeated-measures ANOVA (RM-ANOVA) or nonparametric analyses (Friedman's ANOVA with follow-up Wilcoxon tests). The RM-ANOVAs tested for changes in scale scores over baseline, week 4, and week 8 visits across the entire sample (time effect), as well as differences in these changes over time between treatment groups (time-by-treatment interaction). Effect size of time to change was compared using a partial eta-square estimate of effect size. An eta-squared less than or equal to 0.01 is considered small; 0.06 is considered medium; and, 0.14 is considered large.
