^1.

Multivariable adjusted models included past 30-day combustible tobacco use, gender, race/ethnicity, asthma, physical activity, and past 30-day alcohol use; missing values multiply imputed

^2.

Ordered logistic regression; adjusted odds ratio represents the ratio (relative to reference) of odds of being in a more frequent category of dry mouth, holding all covariables constant

^3.

Negative binomial regression; adjusted ratio represents ratio of Shortened Xerostomia Inventory score in the category of interest relative to reference, holding all covariables constant

Abbreviation: OR = odds ratio
