Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Patients taking simvastatin, lovastatin, atorvastatin, or pravastatin for at least 3 months and those who had never used statins were considered to be eligible for participation. We included patients scheduled for elective surgery (October 2009 between June 2010) in this comparative, prospective, nonrandomized study.
