[Feature Request] Missing variables in ADEG and ADEX

[edelarua]

Hello again,

While testing safety templates in scda.test, we found that the following variables are missing from the ADEG and ADEX datasets:

• [ ] AVALU (missing from both ADEG and ADEX - if difficult, we could add this into our pre-processing steps)
• [ ] WORS02FL (missing from ADEG)
• [ ] PARCAT2 (missing from ADEX)

If you require any further details please let me/the SME team know.

Thanks!

Hi @edelarua , thanks for the feature request! Could you please provide detailed derivations for ADEG.WORS02FL and ADEX.PARCAT2?

Could you please provide detailed derivations for ADEG.WORS02FL and ADEX.PARCAT2?

Hi @kaz462,

WORS02FL has label "Worst Post-Baseline Observation" and is equal to "Y" when ABLFL != "Y" and grade/level is worst on a per-patient basis.

PARCAT2 has label "Parameter Category 2" and correlates with the ACTARM variable. It is described as "Name of Actual Treatment. Addtional identification information may be added to uniquely identify a study treatment, if necessary."

AVALU and WORS02FL won't be added to pharmaverseadam per discussion from https://github.com/pharmaverse/admiral/issues/2490

PARCAT2 has label "Parameter Category 2" and correlates with the ACTARM variable. It is described as "Name of Actual Treatment. Addtional identification information may be added to uniquely identify a study treatment, if necessary."

For PARCAT2, @edelarua could you please provide more details on what values need to be populated for each parameter?

e.g., we currently have PARCAT1 with the following values mapped to PARAM

> dplyr::count(adex, PARCAT1, PARAMCD, PARAM)
# A tibble: 19 × 4

Hi @kaz462,

As an example, the PARCAT2 variable in our current dummy data has values "Drug A" and "Drug B". This variable is used for row-wise stratification of our tables, so the names of the levels are not particularly important.

Decision from call: add PARCAT2 on NEST side as there are only a few templates that use it and the pharmaverseadam ADEX only has one treatment
