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.
We suggest spending no more than 5 minutes on a review. The other tabs beside Your review are background for assessment, not under review.
Summary
EditUnder reviewWhat this benchmark meansREADME.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: derive TRT01A, the actual treatment for the first
period, as a single subject-level record from exposure records.
Input: demographics records with exposure records carrying
administered treatment (EXTRT), start date (EXSTDTC), and
sequence number (EXSEQ).
Variables:
TRT01Awould be the treatment from the chosen exposure record.
Note: the administrations are placed in start-date and sequence-number order with no statement of which end supplies the treatment, so a subject whose administrations disagree has more than one possible answer. The run is rejected before any data is read and no artifact is accepted.
How to fix
State which end of the order supplies the treatment alongside the order itself. For the earliest treatment:
intermediates:
- id: DOSING
dataset: EX
key: [STUDYID, USUBJID]
order_by: [EX.EXSTDTC, EX.EXSEQ]
keep: first
Use the latest end only when the intended result is the latest treatment.
