Table 1.
Mean values ± standard deviation for high and low CR groups.
| High- CR (n = 8) | Low- CR (n = 12) | P values | |
|---|---|---|---|
| Age | 67.3 ± 7.4 | 69.7 ± 6.6 | p > 0.05 |
| Educational Level | 4.5 ± 0.7 | 2.4 ± 0.7 | p < 0.05* |
| Occupation attainment | 4.5 ± 0.5 | 1.6 ± 0.5 | p < 0.05* |
| CRI score | 9 ± 0.6 | 3.7 ± 1.1 | p < 0.05* |
| Cognitive activity | 4.2 ± 2.3 | 2.8 ± 1.4 | p > 0.05 |
| Physical activity | 2.4 ± 1.5 | 2.7 ± 1 | p > 0.05 |
| Social activity | 1.6 ± 1.2 | 1.7 ± 1 | p > 0.05 |
| Acc. Smaqe | 114 ± 10.7 | 106 ± 14.1 | p > 0.05 |
Significant p values are p < 0.05 and marked with an asterisk (*). Both groups differ in their educational level, occupation attainment and CRI scores, but not in the other variables. Acc. Smaqe, accuracy in the modified Stenberg’s memory task.
