Mean/Median Baseline and Mean/Median Change from Baseline in Exercise Treadmill Duration (seconds) at Week 24 (Stage 2) (ITT Population).

1Baseline of Stage 2 is the last non-missing Stage 1 value (last observation carried forward [LOCF]).
2Mean intra-patient percent improvement.
3p-value for the mean is from a paired t-test; p-value for the median is from the Wilcoxon signed rank test.

1. 第二阶段的基线值为采用末次观测值结转（last observation carried forward, LOCF）法得到的最后一个非缺失的第一阶段观测值。
2. 受试者内平均百分比改善幅度。
3. 均值对应的p值来自配对t检验；中位数对应的p值来自威尔科克森符号秩检验。
