Baseline scores, the amount of changes and group differences in change of the MoCA-J score.

The difference in change between the groups is the change in the SoroTouch group minus the change in the Control group. Analysis of covariance was conducted, setting the baseline scores as covariates. The group difference was not observed in the change in the total and domain scores after the intervention. Some items could not be analyzed for the following reasons: 1) too few people changed; 2) the scores were the same for all; and 3) the scores were not a continuous number, e.g., only 0 or 1; these are indicated as not applicable (NA).
