SECONDARY outcome

Timeframe: Day 7

Population: The Full analysis set population contained 24 patients. 2 patients were not included in this analysis due to missing data.

General assessment of the treatment on a integer scale that ranges from 1 to 10. The lower end of the scale is indicated with the term "Not satisfied" and the higher end with the term "Very satisfied". Question asked: How do you generally regard the treatment?
