i2b2 is the Informatics for Integrating Biology and the Bedside software, developed at the NIH-funded National Center for Biomedical Computing (NCBC) based at Partners HealthCare System. i2b2 is a self-service tool that allows researchers to explore and query the deidentified and aggregated PEGS data by building queries to assist with cohort discovery and identification. Researchers and collaborators are encouraged to use i2b2 for the PEGS data at various stages of their research, including but not limited to:

  • Data exploration
  • Feasibility analysis
  • Study design specifications
  • Cohort identification
  • Cohort demographics
  • Case/Control counts for phenotype of interest
  • Aggregated counts for exposure of interest

Researchers and collaborators can explore the PEGS data and save the results of their queries using i2b2 as a free self-service tool. For i2b2 related issues, please email

All data on this website are reported from PEGS Data Freeze 1.1 created on 7/26/2021.
