Evidence-based and precision medicine two of a kind

In the last two decades, an enormous expansion of evidence has been produced in upper airway research. When writing the first EPOS document in 2005 only 5 RCT per year were performed in the area of CRS, in 2007 this changed to 25 per year and it became even higher in the recent years. Randomized Controlled Trials (RCTs) are the "gold standard" for evaluating treatment outcomes providing information on treatments "efficacy". To make life easier for clinicians, systematic reviews and meta-analysis further condense the available evidence.
