Standardized Multiple Regression Model With Partial Correlation Coefficients Between Variables and Access Outcome
| Partial r | SE | P Value | |
|---|---|---|---|
| FTE | −0.51 | 0.11 | <.001 |
| Clinicians/site | 0.12 | 0.09 | .220 |
| Panel size | 0.22 | 0.10 | .032 |
FTE = clinician full-time equivalent value; r = correlation coefficient; SE = standard error.
Note: We report the estimate of the partial r, SE, and P value via an F test for each independent variable, with the access outcome (days until third next available appointment) controlling for the other 2 independent variables in the standardized multiple regression model. Multiple R2 = 0.22; adjusted R2 = 0.20.
