Legend. Interactions between treatment and time from GEE models are effect sizes for the standardized difference in strategy clustering score outcome gain between memory-trained and control groups. These models are adjusted for age, sex, ethnicity, self-rated health status, and education. 95% CI: 95% Confidence interval.
