  • Notes: The table shows unadjusted and adjusted regression estimates and p-values (in parentheses) of differences in outcome changes between Cooperative groups. Practices from Cooperatives with low experience are the reference group. Adjusted estimates are based on regressions that include practice characteristics (practice location; practice ownership; practice size; practice patient characteristics). Bold denotes statistical significance at the 5% level. All standard errors are clustered at the Cooperative level using bootstrapping.
