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: build the demographics domain with each subject's age (AGE), and
the metadata a data definition describes it by.
Input: collected demographics with the year of birth (BRTHYR) and the
year of the reference start date (RFYEAR), one record per subject.
Variables:
DOMAINisDMon every record.AGEwould be the reference year minus the birth year.
Note: the age is computed by subtracting one year from another, but it is described as collected by the investigator. A value computed here was not collected as it stands, so the description contradicts how the value is made, and the run is rejected before any data is read; no artifact is accepted.
How to fix
Describe the age as derived by the sponsor, with the method a reviewer needs:
submission:
core: Exp
role: Record Qualifier
length: 3
origins:
- type: Derived
source: Sponsor
method: Year of the reference start date minus the year of birth
If the case report form collected the age itself, read that collected value instead of computing it, and keep the collected origin.
