Main Concept of Data cut process
The main idea of {datacutr}
is to provide a standardized
approach to applying a datacut to SDTM datasets.
The process applied by the package is the following,
- create a meta dataset
DCUT
that references all patients to be included within the cut, and the cut date to be used as reference (normally the Clinical Cut-off Date that data has been cleaned to).
- using
DCUT
as reference, records can be removed from the SDTM data that are either a) patients not part of the referenceDCUT
, or b) records that can be identified as after the data cut date supplied.
