ctrdata-trial-concepts {ctrdata}R Documentation

Trial concepts implemented across registers

Description

ctrdata includes (since version 1.21.0) functions that implement selected trial concepts. Concepts of clinical trials, such as their start or status of recruitment, require to analyse several fields against various pre-defined values. The structure and value sets of fields differ between all ctrdata-registers. In this situation, the implemented trial concepts simplify and accelerate a user's analysis workflow and also increase analysis consistency.

Details

The implementation of trial concepts in ctrdata has not been validated with any formal approach, but has been checked for plausibility and against expectations. The implementation is based on current understanding, on public data models and on scientific papers, as relevant. As with other R functions, call help("f.startDate") or print its implementation code by entering the name of the function as command, e.g. f.startDate. Please raise an issue here to ask about or improve a trial concept.

The following trial concepts can be used by referencing their name when calling dbGetFieldsIntoDf (parameter calculate). Concepts will continue to be refined and added; last updated 2025-07-18.
