| 2. IEAA | 1 | .30 | −.26 | −.35 | −.33 | −.05 | .09 | −.04 | −.34 | |
| 3. EEAA | 1 | −.23 | −.26 | −.28 | −.41* | −.31 | −.12 | −.20 | ||
| 4. MMSE-KC | 1 | .56** | .64** | .42* | .39* | .62** | .73** | |||
| 5. Word List Memory | 1 | .81** | .50** | .31 | .54** | .65** | ||||
| 6. Word List Recall | 1 | .54** | .28 | .44* | .56** | |||||
| 7. Word List Recognition | 1 | .54** | .38* | .63** | ||||||
| 8. Digit Span Forward | 1 | .65** | .60** | |||||||
| 9. Digit Span Backward | 1 | .55** | ||||||||
| 10. FAB | 1 |
Note. MMSE-KC = Mini-Mental State exam in the Korean version; IEAA = intrinsic epigenetic age acceleration; EEAA = extrinsic epigenetic age acceleration; FAB = frontal assessment battery.
