Comment:

Answer B

The use of levels of evidence, in evidence-based medicine, is a means by which the reader can stratify, in a standardised manner, the evidence according to its quality. A number of systems have been designed for this purpose, including that produced by the Oxford Centre for Evidence-Based Medicine [1]; a modified version of which is used by the European Association of Urology clinical guidelines to formulate its grades of recommendations.
