NAT1 allele frequency in AD cases and controls.
| NAT1 ALLELE | AD CASES (N = 147) | CONTROLS (N = 111) | OR (95% CI) |
| 1*4 | 220 (0.75) | 176 (0.79) | 1.00 |

| 1*14A | 5 (0.02) | 4 (0.02) | 1.00 (0.27, 3.78) |
| TOTAL | 294 (1.00) | 222 (1.00) | - |
The number and frequency (in brackets) of NAT1 alleles in 147 AD cases and 111 controls is shown. The OR of AD to non-disease is given with 95% CI for each NAT1 allele (with NAT1*4 as the reference group).
