We want to make sure we have at least a few trials to include in The People’s Review to answer our question. So, the team behind-the-scenes had a quick check to make sure there were trials available already looking at the topics considered. Scroll through the list to see the questions we had to exclude because no randomised trials have been published so far about these interesting topics. Researchers, if you are listening... The people have spoken! Consider starting a randomised trial on one of these questions! They are needed and wanted!

Systematic reviews of randomised trials are the best way to figure out if a healthcare intervention works (which is why we've chosen this type of review for The People's Review). Some of you sent in some great questions that would be super interesting to explore. However, we would need to include other types of studies (not trials) to answer them -- so we couldn't bring them through to Stage 2. Randomised trials are not always the most appropriate way to investigate some health research topics. Sometimes other designs are more appropriate, practical and safe. Therefore questions that would be better answered with reviews including different types of studies (other than trials) were excluded.

We totally understand that what is relatable to you might not be relatable to someone else. As a team, eight of us have had a look at the questions… and even between the eight of us we disagreed about what ‘relatable’ actually means. In the end, we interpreted a ‘relatable’ question as one that is applicable to most or at least a lot of people. With that in mind, we excluded questions that were looking at a specific disease or group of people. After all, we want a review of an intervention that is cheap and readily available to people around the world.

An important step when starting any systematic review is considering the resources you have. Because the purpose of The People's Review is to learn together about a systematic review we want this to be our main focus. If we choose a very big (e.g. a review that would include 100's of trials) and complex review things can get messy and complicated very quickly. So we have excluded some questions because they are likely going to be giant, complex reviews that we won’t be able to manage.
