What does the primary outcome measure?
incidence of CPB at the University Hospital Basel (number) (time frame: from January 1st , 2008 until December 31st, 2028). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
