Demographics and neuropsychological variables for MCI groups.
| MCI | Statistics | ||
|---|---|---|---|
| Carriers | Non-carriers | ||
| N | 126 | 127 | – |
| Gender (M/F) | 80/46 | 88/39 | p = 0.33& |
| Age (y) | 74.17 (6.91) | 76 (7.97) | U(6542) = − 2.51, p = 0.01+ |
| Age range | 56.8–88.9 | 54.6–89.8 | – |
| Education (y) | 15.63 (3.03) | 15.61 (3.38) | U(7878) = − 2.21, p = 0.83+ |
| MMSE | 26.97 (1.85) | 27.17 (1.83) | U(7492) = − 0.87, p = 0.38+ |
| Mean cortical thickness (mm) | 2.23 (0.12) | 2.23 (0.14) | U(7902) = − 0.17, p = 0.86+ |
Age, Education, MMSE, and Mean cortical thickness values are represented by means and standard deviations. Gender (M/F) is represented by the number of subjects. Significant set at p < 0.05. The superscripts “&” represents χ2 test; “+” represents the Mann–Whitney U test.
Key: MCI mild cognitive impairment; Carriers: ApoE4-positive; non-Carriers: ApoE4-negative; M male; F female; y years; MMSE mini-mental state examination.
