Impute last EXENDTC per subject and treatment to cutoff date when absent.

In some instances, particularly when analyzing non-cleaned SDTM data from ongoing clinical studies with multiple-dose administrations, the last administration epoch in EX may have an empty EXENDTC field. Often, the underlying reason is that the respective subjects are still on treatment. This function replaces the missing EXENDTC with the global data cut-off date, cut_off_date.

Usage

impute_exendtc_to_cutoff(ex, cut_off_date = NA, silent = NULL)

Arguments

ex

The EX domain as data frame.

cut_off_date

The cut-off date.

silent

Suppress messages. Defaults to nif_option setting if NULL.

Value

The updated EX domain as data frame.
