CEBM has developed a widely adopted [6] systematic hierarchy of the quality of medical research evidence, named the levels of evidence. Systematic reviews of randomised clinical trials (encompassing homogeneity) are seen as the highest possible level of evidence, as full assessment and aggregated synthesis of underlying evidence is possible.
