IF
the level of risk were not coarsened you might have additional info.

Am I correct that you only coarsened the risk level to have "repeats"?
If risk were not coarsened the most complex interaction would not be estimable but all lower order interactions would be.

What do other list members think of trying an analysis without coarsening the risk variable?
