NOTES Results were adjusted for individual age, sex, race or ethnicity, health status, and ZIP code median household income. Primary care physician supply and specialist supply variables were included in “all physicians.” None of the relative rates is statistically significant. Test for trend indicates whether there was a stepwise effect observed across increasing quintiles of supply. Primary care and specialist physician supplies do not add to totals because they represent median hospital service area supplies per quintile. [R] denotes referent.
