How do you explain hierarchy of evidence?

There is broad agreement on the relative strength of large-scale, epidemiological studies. More than 80 different hierarchies have been proposed for assessing medical evidence.
What is the hierarchy of EBP?
EBP hierarchies rank study types based on the rigour (strength and precision) of their research methods. Different hierarchies exist for different question types, and even experts may disagree on the exact rank of information in the evidence hierarchies.
