Note: The assertion that practice setting is the most important factor of those included in the model is substantiated
by the fact that practice setting accounts for more than 90 percent of the explanatory power of the
full model. R-square for full model=0.0730; R-square for model with practice setting only=0.0687.
1 Practice had IT support for qero or one of five specified patient care functions.
