Sample size differs because some dentists failed to provide some responses to the clinical scenarios. The region variable was used as a covariate in all analyses. Gender and years since graduation were also used as covariates for analyses involving non-prescription and prescription fluoride because of significant associations with the frequency of recommendation for these agents.
