In the Original Research That Was Carried Out to Assess

In the original research that was carried out to assess whether quality outcomes differed in various states, the analysis was completed by:

A) Comparing the 12 states with the highest overall quality of care and the 9 states with the lowest quality of care
B) Comparing the 9 states with the fewest racial/ethnic disparities in quality of care with the 12 states with the most racial/ethnic disparities in quality of care
C) Researching the mean number of active physicians per 100,000 in each state in both groups
D) Using Census data to identify the percent of the total population who are minority and the 9 percent with incomes below the poverty lie in each state
E) All of the above were steps taken
F) None of the above were steps taken
