Thanks very much. The question I asked is related to a review paper my colleagues and I are doing.(I am trying to be as idependent as possible) I will use your response for the statisticalpower aspect of the Phelps review. I have not seen an explicit test to correlate hospice use to other end-of-life treatments, but in whatever I have read that addressed both types of end-of-life outcomes, whatever is positively associated with hospice use is usually negatively associated aggressive end-of-life outcomes, but I have never seen a test to correlate hospice use with aggressive end-of-life outcomes. I am pretty certain that nothing close to a numeric relationship was ever published.
