Table 2.
Linear regression results to assess whether the rating of asthma control depends on the percent of minority patients in the practice as presented by the interaction terms in each regression model.

Adjusted for pediatrician’s race, employer, weekly volume of asthma patients, years since graduation, location and percent of public health insurance patients.
§
p Value is for interaction terms to test whether the effect of each asthma status indicator on the likelihood to increase treatment differed by proportion of African-American/Latino patients.
