Adjusted odds ratios (ORs, AORs) and 95% confidence interval (CIs) of oral cancer associated with MTNR1A genotypic frequencies and smokers among 571 betel nut consumers.

ORs with their 95% CIs were estimated by logistic regression models.AORs with their 95% CIs were estimated by multiple logistic regression models after controlling for age, gender, and alcohol consumption.a Individuals with the wild-type genotype who did not smoke.b Individuals with either at least one mutated genotype or who smoked.c Individuals with both at least one mutated genotype and who smoked.Adjusted odds ratios (ORs, AORs) and 95% confidence interval (CIs) of oral cancer associated with MTNR1A genotypic frequencies and smokers among 571 betel nut consumers.
