^† From a site-level (13 sites for specialists and 12 sites for non-specialists) fixed-effects logistic regression model adjusted for sex, education, age, race and ethnicity, employment, marital status, and health status. In the specialist group, 2 of the sites were dropped due to perfect prediction in Diet. In the non-specialist group, 1 site was dropped for each of the models due to perfect prediction, except for Diet where 2 sites were dropped. All specialist samples included 1,313 individuals, except for Diet, which had 1,278 individuals. All non-specialist samples included 710 individuals, except for Diet, which had 662 individuals, and Body Treatments, which had 702 individuals. The models controlled for differences at the site level using fixed effects for the sites.
