yamaa As a clinical trial statistician or programmer, answer two short questions in Your review: the task and the inputs. Agreeing with both approves this benchmark; disagreeing with either needs a comment. Propose a fix with the Edit button on any source file, or add it to your comments.

Summary
EditUnder reviewWhat this benchmark meansREADME.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: carry each subject's disposition event (EOSSTT) and the days
from the last dose to it (EOSPDY) onto the subject-level analysis dataset.
Input: collected demographics with the study day of the last dose
(TRTEDY), one record per subject, and collected disposition events with
their category and study day (DSSTDY).
Variables:
TRTEDYwould be the study day of the last dose as collected.EOSSTTwould be the subject's disposition event.EOSPDYwould be the study day of that event minus the study day of the last dose.
Note: the disposition events are checked to be one per subject before any record is built, but each event also carries a value computed from the record being built, its last dose day. A check made once cannot cover events whose values change record by record, so the run is rejected before any data is read and no artifact is accepted.
How to fix
Keep the uniqueness check on the event itself, and compute the days from the last dose in the subject-level column instead:
- name: EOSPDY
type: int
label: Days From Last Dose to End of Study
derivation: "DISP.DSSTDY - TRTEDY"
with DAYSPOST removed from the event's derivations.
