Table 1.
Distribution of ApoE4 carrier status and the frequency of ApoE ε4 allele in the population of AD, DLB, and control groups.
| ApoE4 carrier* | ApoE ε4 allele** | |||
|---|---|---|---|---|
| Positive | Negative | Positive | Negative | |
| C | 51 (18.3%) | 228 (81.7%) | 57 (10.2%) | 501 (89.8%) |
| AD | 63 (42.0%) | 87 (58.0%) | 72 (24.0%) | 228 (76%) |
| DLB | 21 (42.0%) | 29 (58.0%) | 27 (24.0%) | 73 (76.0%) |
Numbers in parentheses represent the frequencies of ApoE4 carrier or ApoE ε4 allele. C, control group; AD, Alzheimer's disease group; DLB, dementia with Lewy bodies group.
*
Significantly different between AD and control groups (p < 0.0001), and between DLB and control (p = 0.0004).
**
Significantly higher in AD (p < 0.0001) and DLB (p < 0.0001) than in the control group. No significant differences in rates of ApoE4 carrier status and the frequencies of the ε4 allele between AD and DLB.
