FAQs

There is a small “triangle” to the right of each item of evidence returned in the results from a search (circled in red in the screenshot below).

These “triangles” actually represent pyramids.

In evidence-based practice it is common to represent the quality of the evidence using a pyramid where, the higher up the pyramid, the better the quality of information is likely to be. So, items 8 and 10, above, look like they will probably be systematic reviews, while item 9 is a primary study. It is important to think about the quality of any study design you use and consider whether the methods are valid so you can judge whether the results are likely to be trustworthy or not.
