Comparison of ApoE genotypes between MCI, SCI and AD
| MCI | p | SCI | p | AD | |
|---|---|---|---|---|---|
| All genotyped | 118 (100) | 140 (100) | 67 (100) | ||
| ApoE3/E3 | 55 (46.6) | 0.753 | 68 (48.6) | <0.001 | 13 (19.4) |
| ApoE4/E4 | 13 (11.2) | 0.121 | 8 (5.7) | <0.001 | 19 (28.4) |
| ApoE3/E4 | 42 (36.2) | 0.889 | 51 (36.4) | 0.050 | 34 (50.7) |
| ApoE3/E2 | 8 (6.9) | 0.463 | 13 (9.4) | 0.037 | 1 (1.5) |
Figures are numbers with percentages in parentheses. AD and MCI group means and proportions were compared to SCI. p values correspond to χ2 tests. There was a statistically significant difference between ApoE genotypes between the SCI and AD groups, with no significant difference between the SCI and MCI groups.
