Note. Data are mean values per community health center for each year. Chi-square tests for dichotomous variables are from logistic regression models adjusted for demographic variables from Table 1 ▶ (age, gender, race, poverty status, urban/rural character, and geographic region). F tests for continuous variables are from generalized linear models adjusted for the same demographic variables.
