yamaa As a clinical trial statistician or programmer, challenge anything in this benchmark: describe a problem in Comments, or propose a fix with the Edit button on any source file.
- Task: Is this a specification error a study team could realistically make, and should the build stop on it rather than continue?
- Inputs: Do they trigger the failure for the reason the summary gives?
- Expected failure: Is this the right error, raised at the right point, and would it tell the programmer what to fix?
The other tabs beside Comments are background for assessment, not under review.
Summary
EditUnder reviewWhat this benchmark meansREADME.mdGoal: complete the analysis start date (ASTDT) of each
adverse event (AE) from the collected start (AESTDTC), supplying
a day only where the collected text already carries a month.
Input: collected event records carrying the reported term
(AETERM) and the collected start (AESTDTC).
Variables:
ASTDTwould be the analysis start date completed fromAESTDTC: the 15th of the collected month for a year-and-month start, the collected date unchanged when it is already complete, and missing for a year-only start, because a start must carry at least a month. No collected start can therefore ever take a supplied month, so the written month6is unreachable and the run is rejected before any data is read. No artifact is accepted.
How to fix
Drop the month: nothing the policy accepts can use it.
date_impute:
source: AE.AESTDTC
day: 15
minimum_source_precision: month
A year-and-month value such as 2023-06 then becomes 2023-06-15.
A year-only value such as 2023 is still left missing, because the
declared minimum forbids supplying both a month and a day.
