Baseline, Follow-up, and Predicted Follow-up RBANS scores, standardized z scores, and p values for Observed versus Predicted Follow-up scores in community amnestic MCI participants (n = 64)
| Observed Baseline | Observed Follow-up | Predicted Follow-up | z score | p Value | |

| Language | 98.3 (11.4) | 96.0 (11.2) | 102.1 (7.1) | −0.62 (1.0) | 0.001 |
| Attention | 95.9 (14.1) | 97.8 (15.4) | 100.2 (8.9) | −0.19 (0.9) | 0.09 |
| Delayed Memory | 80.2 (12.7) | 87.0 (18.4) | 91.0 (8.9) | −0.38 (1.2) | 0.02 |
| Total Scale | 89.2 (10.4) | 91.8 (12.8) | 95.5 (7.5) | −0.32 (0.8) | 0.003 |
Note: RBANS = Repeatable Battery for the Assessment of Neuropsychological Status, p value = significance of one-sample t tests examining whether z scores differed from expectation (z = 0) based on the normal distribution of z scores.
