Consider the pyramid to be a visual representation of the entirety of clinical biomedical information. Resources at the bottom of the pyramid are plentiful but are not necessarily Evidence-Based in their approach or findings. Moving up the pyramid, resources are developed using more robust methodology which lessens bias and leads to stronger Evidence-Based findings but are fewer in number. The list of resources on the Evidence-Based Resources tab above are listed hierarchically top to bottom based on the pyramid. Start at the top of the list and move down until you find a resource that answers your question – you can then feel confident that you have discovered the Best Evidence available on your topic.
