Liberating the literature

Pyramids are back

In the recent redesign we removed the evidence pyramids in the results panel, after some feedback we have just reinstated them:

The evidence pyramid concept is explained in this diagram and accompanying text:

Evidence pyramids are not perfect, for instance a poor systematic review is no match for a good RCT. But our evidence pyramids are useful in attempting to convey the potential level of evidence for each result. We use 5 levels in our simplified pyramid and they are colour coded to match the narrative description of the record (e.g ‘systematic review’ is green or ‘key primary research’ is dark blue) and that corresponds to the same colour in the filter results column:

In short, these are a simply tool to help convey the potential robustness of the evidence.

More guidelines

As you may be aware Trip has the largest dedicated collection of guidelines and it’s important to us that we continue to develop this valuable resource.

Following on from the new guidelines added in May we have just added a further 6 sites.

NOTE: If you find a guideline not in Trip then please let us know – it’d be great to hear from you.

Update: New developments on Trip

Just under a month ago we posted a list of four potential improvements to the site (click here for details), alongside an option for user to vote on which they’d like to see. The results so far are as follows:

I’m interpreting this as a clear vote for the first idea (improved search) and then the next two are roughly tied. So, how will this translate in to action? Here’s the plan:
  • Improved search: We have asked a tech/data team to come up with options for improving the sensitivity/specificity of the search. From there we will aim to implement the changes ASAP.
  • Search support: We’re really excited to see this do so well. We need to have a planning session to explore what this might look like, this will require our techie and design teams to come together. This is likely to be after we’ve rolled out the improved search.
  • Quality scoring: We have already done all of the background work on the guideline quality scoring and we can roll this out when we get developer capacity. After that we have already completed a quality scoring method for systematic reviews, we just need to spend some time verifying that.

All very ambiguous with the dates – as we still have the indexing to finish (see What next? for further details) but while we wait for developer time we’re working hard in the background to bring these to you as quickly as possible.
