Risk of Bias scores for controlled trials

We’ve been working with RobotReviewer for a number of years. They do two things for us:

  • Highlight all the controlled trials in PubMed with a high degree of accuracy
  • Assess these trials for bias using their amazing automated systems (see this earlier blog when we first started working with them).

RobotReviewer have improved their systems making bias and trial identification even better and to ‘celebrate’ this we’ve made some changes to Trip.  We’ve altered the way bias scores are displayed in Trip and we’ve now created a filter so you can choose to only show those trials with a low estimated risk of bias (labelled “Controlled trial quality: predicted high”):

 

This is a big improvement in helping people easily locate high quality evidence, as such we’re delighted.

Oh yes, for the data nerds, as of a few days ago there were 552,463 controlled trials in PubMed!

Changes on the results page

We’ve had a bit of a re-jig of the results page.  This is the old format (note the Q&A reference at the top and the search suggestions ‘Trip users also search for’ towards the bottom):

 

The new format has reversed the position of these:

The rationale is simple, the search refinement section has been moved to the top as users might well see a large number of results and want to refine straightaway. The Q&A, where it was, was confusing and appeared too early in the search ‘journey’. It makes more sense when a user has gone through some results and is thinking there may be no answer.

Oh yes, the search refinement area (at the top) is a rollover – if you rollover it expands:

As ever, comments welcome!
