Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
8709 patients were randomized from May 2007 until December 2008 in 196 participating hospitals in 36 countries across five continents.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
80 patients were excluded because there was no validly signed consent available during monitoring and 2 patients retracted their consent before the procedure, resulting in a total of 8709 patients randomised.
