  1. aORs were adjusted for: age at diagnosis (≤30, 31-49, 50-69, and ≥70 years), the lower age group being the referent class; alcohol consumption (never, social, and regular drinkers), never drinkers being the referent group; and smoking habits (smokers/non-smokers), non-smokers being the referent group.
  2. Data in bold highlights the statistic significant results (p < 0.05). P values are adjusted by unconditional multiplicative logistic regression.
