In general, the hierarchy of studies for obtaining evidence is: Systematic reviews of randomised controlled trials (RCTs). Evidence-based practice is a way to ensure the integration of best research evidence with clinical expertise and patient values (Sackett, Strauss & Richardson, 2000 as cited in Akobeng, 2004).
