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: keep each adverse event's analysis start time (ASTTM) as a
time of day.
Input: adverse event records, each identified by study, subject and
sequence, carrying the reported term and the collected start as ISO 8601
text (AESTDTC).
Variables:
ASTTMwould hold the start's time of day as atime, so2025-03-04T08:30:15gives08:30:15. Only a date and time has a time of day, and the start is still text that nothing has read as one, so the run is rejected before any data is read and no artifact is accepted.
How to fix
Complete the collected start into a date and time first, deciding what a start collected without its time or without its seconds becomes, and take the time of day from that column:
- name: ASTDTM
type: datetime
derivation:
impute:
type: datetime
source: AE.AESTDTC
time: first
- name: ASTTM
type: time
derivation:
to_time:
source: ASTDTM
Pair the time with the imputation flag of ASTDTM, so a start whose time
was supplied is not read as a collected midnight.
