For variables not normally distributed, medians and interquartile ranges are reported. Intravascular ultrasonographic efficacy end factors are reported as medians, with distribution-free 95 percent self-confidence intervals, and treatment groupings were compared with the usage of evaluation of covariance on rank-transformed data after adjustment for baseline values and geographic region. For the transformation in the principal efficacy end point, PAV, a sample of 450 sufferers in each treatment group was required for 90 percent power at a two-sided alpha level of 0.05 to identify a nominal treatment difference of 0.65 percent, assuming a standard deviation of 3.0 percent.
