trace data
Description
These data are from screening to the TRACE study, a comparison between the angiotensin converting enzyme inhibitor trandolapril and placebo ford large myocardial infarctions. A total of 6676 patients were screened for the study. Survival has been followed for the screened population for 16 years. The current data has been prepared for a poisson regression to examine survival. The data has been "split" in 0.5 year intervals (plitLexis function from Epi package) and then collapsed on all variables (aggregate function).
Format
A data frame with 1832 observations on the following 6 variables.
- Time
Time after myocardial infarction, in 6 months intervals
- smoking
Smoking status. A factor with levels (Never, Current, Previous)
- sex
A factor with levels (Female, Male)
- age
Age in years at the time of myocardial infarction
- ObsTime
Cumulative risk time in each split
- dead
Count of deaths
