metalite.ae is an R package designed for the analysis of adverse events (AE) in clinical trials. It operates on ADaM datasets and adheres to the metalite structure. The R package streamlines the process of generating production-ready tables, listings, and figures as outlined in the AE summary chapter and the specific AE chapter of the R for Clinical Study Reports and Submission book. The package encompasses the following components:
Highlighted features
- Avoid duplicated input by using metadata structure.
- For example, define analysis population once to use in all adverse events analysis.
- Consistent input and output in standard functions.
- Streamlines mock table generation.
