Jay, I don't have my references with me, but I think the data can be found in one of the ISIS trials, perhaps ISIS-2. Try ISIS-2 Randomized trial of intravenous streptokinase, oral aspirin, both or neither among 17,187 cases of suspected acute myocardial infarction. Lancet 1988 ii: 349-360.

So now you will need to give us a ref. to Prof. Petro's analysis, if only so we can rub it in to those who haven't been there. :) I'll shortly try a google on "Petro" to see what happens. But when clearly idiotic questions are raised, and demonstrated such, we need to have the definitive analysis handy.
