About the "CARE - Concept Demographics Histograms" Web Client Plugin



This plugin is part of the CARE (Cohort Analysis & Refinement Expeditors) Tool Set developed as a result of feedback and suggestions from the i2b2 users community in the University of Massachusetts Medical School. As its name implies, the purpose of this tool set is to facilitate and expedite the analysis of the cohorts (i.e. a subset of a patient set) and therefore hopefully the refined usage of those particular cohorts in a study.

This plugin provides the following main functions:



  1. Navigate to the "Specify Data" tab. Drag and drop a Patient Set and one or more concepts (ontology terms) onto the appropriate input boxes:
  2. Finally, select the "View Results" tab to wait for and view the generated demographic histograms.


  - Note that in any of these cases, the updates of 'Elapsed time' and 'estimated remaining run time' will be quite infrequent, as updates from the server (i2b2 hive) will most likely take a long time,     and far and few in-between, if any.
