Limitations
This post-hoc analysis is subject to physician selection and participation bias, however, if the bias is operative in a similar fashion for PCPs and specialists, our findings are balanced, though not necessarily representative of the overall physician population. Selection bias may have also resulted in the selection of physicians who were interested in cholesterol lowering through their prior participation in similar programs. If this selection bias was present then our findings of the care gap are even more pronounced indicating treatment inertia even among those more likely to be skilled in the art of LDL-C lowering.
