结局指标
主要结局
CogState Groton Maze Learning Task (GMLT) and One Card Learning Task (OCLT) Standardized Composite Score at Day 14
时间窗: Baseline and Day 14
The GMLT and OCLT standardized change composite score will be calculated as the mean of the GMLT and OCLT standardized change from baseline scores. Least square means were derived using a mixed effects repeated measures model with protocol scheduled assessment day, treatment group, baseline score, and assessment day-by-treatment interaction as fixed factors, center as a random factor, and baseline score as a covariate. Scale range from negative infinity (worst value) to positive infinity (best value).
