Stages of Methods Projects

Sentinel develops a wide range of methods to enhance medical product safety assessment.

Early Stage Methods Projects

Early stage methods projects represent truly novel ideas and innovations. They require completion of proof-of-concept work.

Mid-Stage Methods Projects

Mid-stage methods projects focus on methodological techniques showing statistical or epidemiological value. But, they have not been fully applied in the Sentinel Common Data Model (SCDM).

Later Stage Methods Projects

Later stage methods projects create a prototype to inform production-ready analytic tools.
