Pretraining and posttraining estimated means with 95% confidence intervals in the intention-to-treat group. For each outcome measure, the P-value and Cohen d effect size estimate is from the training group (experimental treatment (ET) vs active control (AC)) × time interaction, corrected for the significantly different sex distribution between groups. In (A) Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and (B) overall memory, higher scores are better; in (C) processing speed and (D) Cognitive Self-Report Questionnaire-25 Total, lower scores are better.
