In the image below you will see that the user has restricted the category to ‘Primary research’:

So, you can understand their confusion when the top result is classed as a ‘Systematic review’. This is not the first time it has been raised and, as it’s a recurring source of confusion, we need to act!

The issue arises because we treat ‘Primary research’ to mean ‘Journal articles’. So, in the example above the systematic review was published in a journal – so it gets two categories and we display the highest.

So, our plan is to make sure that any dual category article (primary research and systematic review) is treated only as a systematic review. This means a stricter interpretation of ‘Primary research’ (excluding systematic reviews, which are secondary research).

No timeline on this but it’s in planning. And thank you to Adam T for raising it with us.
