Adjusted odds ratio (AOR) and 95% CI for oral cancer associated with <i>NFKB</i> and <i>NFKBIA</i> genotypic frequencies and cigarette smoking among 444 betel nut consumers.

Odds ratios (ORs) with their 95% confidence intervals were estimated by logistic regression models. Adjusted odds ratios (AORs) with their 95% confidence intervals were estimated by multiple logistic regression models after controlling for age and sex. aPeople with wild genotype but not cigarette smokers. bPeople with either one or more mutated genotypes, or smokers (but not both). cPeople with at least one mutated genotype and also cigarette smokers.
