Individual SNP effects on oesophageal cancer risk in two ethnic groups of South African population.

aMinor alleles are different between the two ethnic groups, hence genetic model indicated in brackets was investigated in Mixed Ancestry group. Significant associations are printed in bold.AOR, odds ratio adjusted for age, gender,smoking status, alcohol intake, place of birth and family history of cancer; CI, confidence interval; ND, not determined (zero genotypes were found in one genotype group).
