PRIMARY outcome

Timeframe: 56 days

Population: In this table, there are 16, 18 and 14 subjects in the 42mg/42mg, 21mg/42mg and Placebo/42mg group, respectively. This is a change-from-baseline analysis, only subjects with no missing values AT BOTH baseline and Day 56 are included in the analysis, so the number of subjects in each group is less than the number of subjects that started the study.
