Table 1.
Mean ± SD values of the demographic characteristics of the sMCI and pMCI patients at baseline. MMSE: Mini-Mental State Examination; Apolipoprotein E (APOE) carrier: There is at least 1 ε4 allele; LHV: Left hippocampal volume; RHV: Right hippocampal volume.
| sMCI (n = 27) | pMCI (n = 27) | F-value | p-value | |
|---|---|---|---|---|
| Age (years) | 71,23 ± 3,98 | 74,81 ± 3,98 | 26,137 | 0,009* |
| Gender (females) | 15 | 18 | Fisher test | 0,577 |
| APOE 4 carrier | 12 | 13 | Fisher test | 0,782 |
| Education (years) | 8,88 ± 4,49 | 8,6 ± 4,49 | 0,0064 | 0,937 |
| MMSE score (first MEG) | 27,34 ± 3,39 | 25,95 ± 3,39 | 32,289 | 0,079 |
| MMSE (second MEG) | 26,19 ± 4,13 | 23,65 ± 4,13 | 29,490 | 0,092 |
| LHV | 0,0024 ± 0,0003 | 0,0020 ± 0,0003 | 97,773 | 0,003* |
| RHV | 0,0025 ± 0,0003 | 0,0022 ± 0,0003 | 55,714 | 0,023* |
p-values for between-groups differences were introduced, and *p < .05. Age differences were assessed with a Mann-Whitney Test. An ANCOVA test, with age as a co-variable, was used for continuous variables and Fisher's exact test for gender and APOE differences.
