Adjusted odds ratio (AOR) and 95% confidence interval (CI) of oral cancer associated with ICAM-1 genotypic frequencies and betel nut chewing among 727 smokers.
The odds ratios (ORs) with their 95% confidence intervals were estimated by logistic regression models.
The adjusted odds ratios (AORs) with their 95% confidence intervals were estimated by multiple logistic regression models after controlling for age, gender and alcohol consumption.
a
Individual with wild genotype but without betel nut chewing.
b
Individual with either at least one mutated genotype or betel nut chewing.
c
Individual with both at least one mutated genotype and betel nut chewing.
