  1. The number and frequency (in brackets) of fast and slow NAT2 acetylators in 45 AD cases and 63 controls is shown. Based on their genotype, AD cases and controls were classified as either 'fast' or 'slow' NAT2 acetylators. Individuals homozygous or heterozygous for the NAT2*4 allele were assigned fast NAT2 acetylators, individuals who carried two 'slow' NAT2 alleles (NAT2*5A, NAT2*5B, NAT2*5C, NAT2*6A and NAT2*7B) in any combination were assigned slow NAT2 acetylators [31]. The OR of AD to non-disease is given with 95% CI for each NAT2 phenotype (with NAT2 fast acetylator as the reference group).
