^*p Value uses an adaptive, step-up Bonferroni procedure for the difference in proportions between the three documentation styles for each quality measure adjusted for clustering by patient; clustering by physician; patient age, gender, race/ethnicity, insurance, median household income by zip code, annual visits per year, number of medications, and number of problems; physician age, gender, and annual number of visits; and intervention group.

^†Percentages are adjusted as is the p value. We do not provide Ns because the denominators are different for each quality measure and because the percentages are adjusted and cannot be calculated directly from the raw numbers.

ACE-I, ACE inhibitor; ARB, angiotensin receptor blocker.
