Although we used individual-level information for these important risk factors, the statistical modeling was not able to completely control for factors related to SES that are substantially different in the exposed versus the comparison population.
The percentage of birth records excluded because of missing information was similar for the study and comparison populations.
3) We did consider as another comparison population
, the continuous FFS population using the 5-percent Medicare sample.
There are three options for the baseline hazard: model the hazard without including a comparison population
, treat the comparison population
as an unexposed group, or replace the baseline hazard function with empirical estimates based on the comparison population
(not included in Table 1).
While other participating practices did achieve lower Medicare spending growth rates than comparison populations
in their local markets, their savings did not meet the 2% threshold to share in the Medicare savings, Mr.

DDV High Risk Minimal Risk Scale (n = 12) (n = 16) (n = 24) L (Lie) Normal 66.
In the secondary analysis, we compared exposure among the case and comparison populations
using conditional logistic regression; we initially analyzed all cases and their corresponding controls, and then only those cases and their corresponding controls meeting the restricted case definition.
