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: derive each subject's date of first exposure to treatment
(TRTSDT), where every subject must have received a dose.
Input: demographics, and exposure records carrying each administration's start date and dose.
Variables:
TRTSDTwould be the start date of the subject's earliest administration with a dose above zero. Every subject is required to have one, so a subject whose administrations all have a zero dose, or who has none, rejects the run with no artifact accepted, instead of leaving the date blank.
How to fix
Correct the exposure data when subject YAMAA-01-103 was dosed: its only
administration records a zero dose. If a subject without a dosed
administration is acceptable, drop require_match: true:
derivation:
source:
variable: EX.EXSTDTC
filter: "EX.EXDOSE > 0"
order_by: [EX.EXSTDTC]
keep: first
The date is then missing for such a subject, and the run counts each one under
absent. Declaring absent beside require_match: true is refused as a
contradiction.
