2D display

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

Definitions

A frontier of trials is defined by those trials for which there are no trials both more recent and published in a journal with a higher Article Influence (AI) Score.
A journal's AI Score is similar to the Impact Factor; however, the AI score takes into account the quality of the citing journals as well as the number of citations in the cited journal.

Research hypotheses:

Meta-analyses limited to trials on the frontier will agree with the full meta-analyses of all trials.
(tentative) The 2D plot, when used with PubMed's related citations utility, can identify additional, relative citations when a list of PMIDs is submitted that was collected by a non-expert searcher.
