DESCRITPTIVE ABSTRACT:
Description of the variables in the GRACE Data used in Chapter 7 and described
in Table 7.4  reference text.

Data for our second example of time-varying covariates were collected for 7.5 years 
from 113 Coronary Care Units (or equivalent) in 14 Countries.  The GRACE registry now contains 
data on nearly 60,000 subjects with an acute coronary syndrome.  Data from GRACE have 
been analyzed and reported in over 50 publications.  For a paper relevant to the current 
example see Granger et al (2003).  A complete list of GRACE publications may be found 
at the Center for Outcomes Research web site, www.outcomes-umassmed.org/grace. 

The data we use are a blinded, specially selected sample of 1000 subjects.  
We thank Dr. Gordon FitzGerald of COR for his help in obtaining the sample and for 
discussing the use of time-varying covariates in this data set with us.
