CHEAR Data Submission and Review Portal – User Manual

This User Manual outlines the Major Functions and Processes supported by the CHEAR Data Submission and Review Portal, and how to use them. This manual is intended for use by Primary Investigators (i.e., “PI”s) and their CoInvestigators. These users will be accessing the portal to upload their study results data, generate CHEAR Participant IDs (PIDs) and Specimen IDs (SIDs), map CHEAR SIDs to PIDs, retrieving lab result data, and other related activities.

Ontology

The Data Center is responsible for creating and maintaining the CHEAR Ontology—a common vocabulary for use in the CHEAR program. The Ontology is evolving with the program and will connect to best-in-class existing vocabularies, thus facilitating the integration of data from multiple studies. The Data Center assists PIs in applying the Ontology to their studies. Services include:

  • Facilitating the mapping of variables from data dictionaries into terms consistent with the CHEAR Ontology

  • Incorporating the study's data into the CHEAR Ontology to support collaborative research across the CHEAR consortium, including pooled analyses from cohort studies participating in CHEAR

  • Developing methods and services for comparing similar variables from different data dictionaries, starting with very basic mappings of equivalent terms and moving into more sophisticated analyses of relationships among variables

  • Providing tools and services to manage the CHEAR Ontology evolution
