  1. In multivariable logistic regression analysis, confounding variables with p < 0.25 in univariable logistic regression analysis are adjusted (age, sex, household income, education level, drinking, residency, and CPI). Variables with asterisk indicate p values < 0.25. Variable with bold indicate p values < 0.05.
  2. CRS chronic rhinosinusitis, CPI newly diagnosed community periodontal index, OR odds ratio, CI confidence interval.
