Participant Flow

The study was conducted at hospital clinics and general practitioners. Patient recruitment started October 20, 2009 and was completed April 30, 2010

Screening, enrollment (2 weeks) and lead-in period (4 weeks). Main reason for not being randomised was due to renal function not meeting inclusion criteria. (Samples taken and analysed after enrollment into the study but prior to randomisation).
