Conservatives and Republicans are thus classifying the population into two key subgroups.
The sample characteristics will be benchmarked against existing data to assess the representativeness of key subgroups.
Analyses were conducted for key subgroups identified in the PLATO trial.
The key subgroups were salaried (permanent, locum and out-of-hours) GPs, GP partners, cardiologists, general physicians and HF nurses.
14 However, detailed national results, including by key subgroups within each country by age and sex, have not as yet been reported.
These associations remained statistically significant after multivariable adjustment and were evident in the overall population as well as across several key subgroups.
Because of small sample sizes in some subsets, validation of the findings in additional studies is needed in key subgroups, including those with diabetes.
First, we developed an analysis plan and identified key subgroups (joint (hip vs. knee) and treatment (surgical vs. non surgical)) and then estimated how large a sample was needed in order to reach minimum targets in the smaller subgroups.
Based on the current design, statements will not be able to be made, without blocking or stratifying, about patients in key subgroups as defined by past evidence by the investigators themselves and by the American Diabetes Association Clinical Practice Recommendations (4).
