Roadmap for Causal Inference in Safety Analysis

Jordan C. Brooks, Alan S. Go, Daniel E. Singer, and Mark J. van der LaanSafety analysis involves assessing the causal effect of a treatment or exposure regimen on one or more outcomes of interest based on observing a sample of subjects over time. The observed data might constitute an observational s...

Shrnutí:Jordan C. Brooks, Alan S. Go, Daniel E. Singer, and Mark J. van der LaanSafety analysis involves assessing the causal effect of a treatment or exposure regimen on one or more outcomes of interest based on observing a sample of subjects over time. The observed data might constitute an observational study or a randomized controlled trial or even a collection of observational or randomized studies.
