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
README.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: carry the first treatment received in TRT01A, one
record per subject.
Input: demographics records plus exposure records carrying the
administration sequence number (EXSEQ), the treatment name
(EXTRT), and the administration start date (EXSTDTC).
Variables:
TRT01Awould contain the treatment name from the earliest exposure record.
Note: the chosen record is named EX, which already names the
exposure records, so a read of EX.EXTRT cannot say whether it
means the treatment of the chosen record or of every exposure
record. The two readings differ whenever a subject has more than one
administration. The name itself is rejected before any data is
read, so no artifact is accepted.
How to fix
Give the record lookup a name that is distinct from every dataset and from the output domain, then read through that name:
intermediates:
- id: FIRSTEX
dataset: EX
key: [STUDYID, USUBJID]
order_by: [EX.EXSTDTC, EX.EXSEQ]
keep: first
# ...
derivation: FIRSTEX.EXTRT
