Using a two-dimensional display to guide selection of citations

 
Citations can be plotted in two-dimensions using date of publication and projected quality of the article or the journal it is published in. In this demonstration, quality is projected by the quality of the journal as measured by the Article Influence (AI) Score
 
Example using list of PMIDs from the trials included in the meta-analysis by Abourbih (2009) (does not include subsequently published ACCORD trial) This frontier performs best when it is wide.
Example using list of PMIDs from the trials included in the meta-analysis by Kansagara (2011)
Example using list of PMIDs from the trials included in the meta-analysis by Musini (2009) This frontier performs best when it is wide.

Frontier width?

  • 0.52 is the width between the NEJM and JAMA
  • 0.55 is the width between the JAMA and the Annals of Internal Medicine

  • If clicked, then the article influence score of articles by known providers of evidence-based resources such as the Cochrane, U.S. Preventive Services Task Force, and others, will be set equal to JAMA.
  • This option has not been formally tested. It may cause trials with article influence less than JAMA and published between the date of the search by the evidence-based review and the date of publication of the review to be removed from the frontier.

The frontier is the red band.
The frontier is defined as containing those trials for which there are no trials both more recent and published in a journal with a AI Score higher than the specified width of the frontier.
