Baseline characteristics were compared by use of the 2 test for
categorical variables and 1-way ANOVA for continuous variables.
The primary end point was assessed by use of sequential pairwise
ANCOVA with adjustment for clinical site, baseline PWT, and
cilostazol use (adjustments done to increase precision of the statistical
comparison). The second baseline treadmill test was used for
the comparison. Separate pairwise models were fit by use of the
given 2 groups being compared. First, SE and ST were each
compared with OMC with a 1-sided level of significance of 0.025.
Given the significance of both comparisons, SE and ST were then
compared with a 2-sided level of significance of 0.05.
