Background:
Preregistration of study protocols in a public repository promotes transparency and reproducibility in pharmacoepidemiological research. Despite its clear benefits, preregistration remains underutilized.
Purpose:
Here, we discuss the advantages of preregistration, explore barriers to its implementation, and highlight existing repositories for preregistering real-world evidence study protocols. A relatively new option is the Real-World Evidence Registry within the Open Science Framework (OSF), which we briefly introduce.
