Figure 1. Proportion of physicians practicing in regions with differing levels of local health care intensity who report being able to obtain the following services when medically necessary. Crude and adjusted results are presented. The number of respondents, shown in parentheses, differs for each question because some questions did not apply to some specialties and because of some item nonresponse (<1% for each question). *Adjusted for all variables included in the final model (patient, physician, and practice characteristics; market-level managed care; local hospital bed and physician supply).
