Multiple logistic regression analysis was applied to estimate the ORs and 95% CIs for depression and anxiety according to indoor ventilation frequency after adjustment for age, sex, urbanization level, educational level, occupational status, marital status, smoking status, drinking status, exercise habits, number of chronic diseases, and fuels. CI: confidence interval; OR: odds ratio.
