LE, level of evidence (Oxford 2011 Levels of Evidence using the protocol for treatment benefits studies, Oxford Centre for Evidence-Based Medicine. http://www.cebm.net/index.aspx?o=5653). Predictability (+)/Predictability (−): with/without statistical significance in prediction of a particular outcome parameter. Predictability (+/−): inconsistent results in prediction of different outcome parameters, e.g., changes in IPSS and Qmax.
