Adjusted odds ratio (AOR) and 95% confidence intervals (CI) of clinical statuses associated with genotypic frequencies of IL-18 -607A/C and IL-18-137G/C in oral cancer patients (n=567).

The odds ratios (ORs) with their 95% confidence intervals (CIs) were estimated by logistic regression models. The adjusted odds ratios (AORs) with their 95% confidence intervals (CIs) were estimated by multiple logistic regression models, after controlling for gender, age, alcohol, tobacco, and areca consumption. > T2: multiple tumor more than 2 cm. Cell differentiate grade: grade I: well differentiated; grade II: moderately differentiated; grade III: poorly differentiated.
