Randomization was performed with the use of permuted blocks and was stratified regarding to clinical site and stratum . All major comparisons between the treatment groups were performed according to the intention-to-treat principle. Two-sided significance testing was useful for all statistical lab tests. The significance of distinctions in mortality between the treatment groupings was assessed with the use of the log-rank check, with adjustment for randomization stratum. Relative risks were expressed as hazard ratios with associated self-confidence intervals and were derived from the Cox proportional-hazards model.21,22 To characterize the time-dependent character of the relative risks of the groups according to the treatment to that they had been randomly designated, hazard ratios had been examined within time intervals of scientific importance: randomization through 30 days, 31 through 365 days, 366 days through 2 years, and any right time after 2 years.
