PRIMARY outcome

Timeframe: Day 1

Population: The efficacy analysis set for each outcome measure includes those patients who received at least one dose of investigational product and for whom a baseline and at least one post-randomisation measurement is available for that outcome measure. Patients were analysed by to randomised treatment in accordance with the intention to treat principle.
