OR, odds ratio; CI, confidence interval; NS, not significant.
1)Unadjusted = crude ORs are calculated from logistic regression models; 2)Fully adj = multivariable adjusted ORs are from logistic regression models adjusted for age, sex, body mass index, education, family income, marital status, and drinking.
*P < 0.05, ***P < 0.001.
