Conditional effect of GMV × CR interactions at three age conditions
| Age condition | Immediate Recall | Short‐delay Recall | Long‐delay Recall | Recognition | ||||
|---|---|---|---|---|---|---|---|---|
| B (SE) | P‐value | B (SE) | P‐value | B (SE) | P‐value | B (SE) | P‐value | |
| Age‐older (+1 SD) | 5.34 (2.13) | 0.014 | 3.41 (2.36) | 0.152 | 0.35 (2.26) | 0.876 | 6.30 (2.22) | 0.006 |
| Age‐mean | −0.58 (1.55) | 0.711 | 0.20 (1.72) | 0.907 | 1.36 (1.65) | 0.410 | −1.57(1.62) | 0.335 |
| Age‐younger (−1 SD) | 4.18 (2.30) | 0.072 | 3.81 (2.55) | 0.138 | 3.08 (2.44) | 0.210 | 3.16 (2.39) | 0.190 |
All episodic memory scores were standardised. Gender, intracranial volume effects were adjusted. GMV, grey matter volume; CR, cognitive reserve index
Age‐older condition = 79.2; Age‐mean condition = 72.9; Age‐younger condition = 66.5. Statistically significant (p < 0.05) associations are indicated in bold.
