Historically, clinical decisions in renal medicine have been challenged by the scarce availability of robust supportive evidence. Not only are the number of randomized controlled trials (RCTs) in Nephrology the third lowest amongst the medical specialties but in many instances the trials themselves are of poor quality. In addition, practice has been further influenced by extrapolation from the outcomes of general population clinical trials which exclude renal patients. The difference between the ideal trial participant and real complex cases encountered in daily practice is well recognized...
