Real World Evidence & Late Phase Retrospective Database Analysis

Retrospective Database Analysis

Retrospective database analyses are a critical component in the hierarchy of evidence. Even product approval does not guarantee payment. Unlike clinical trials, which show efficacy and safety, real-world evidence demonstrates effectiveness, product differentiation and affordability.


CTI has vast experience in retrospective data analyses and can inform the selection of appropriate databases to meet your research objectives.

Our unique phased approach allows for exploratory research to assess database / study feasibility for a specific project, including sample size considerations.


We use advanced statistical and programming techniques, including randomized observation analyses, propensity scoring, difference-in-difference and descriptive and MV regression analyses.

As a full service, global CRO, CTI provides our clients with Medical Directors, regulatory personnel, access to a network of KOLs, and in-house scientific publication development.
