Statistically significant associations (P <0.05) listed in bold.
*
Final adjusted model reflects corrected OR after removing non-significant variables using a backward procedure for variable selection at P <0.25 retention criteria. Adjusted model includes age, race, education, smoking, income, and DM.
†
Adjusted model includes race, dental insurance, and DM.
‡
Adjusted model includes DM.
