All other outcomes are numbers of patients. The number of deaths from all causes is equal to all cause cardiac plus non-cardiac plus hemorrhage. Values in parenthesis are % of total number of patients (1834). p values were determined by the χ2 test for all but peak creatine kinase for which the Kruskal-Wallis test was used. p trend values were calculated using the Cochran-Armitage trend test.

An additional 12 patients died due to hemorrhage over the 3·8 year follow up period (4 at day 1). Adding all cardiac plus non-cardiovascular deaths, plus one death without cause sums to 187.
