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 one subject-level record per subject carrying NEXTSEQ, the
next free adverse event sequence number: one more than the highest the
subject has.
Input: demographics with one record per subject, and collected adverse events with their sequence numbers.
Variables:
NEXTSEQwould be one more than the subject's highest adverse event sequence number.
Note: the request adds one to the subject's sequence numbers joined into one text. A list written as text is not a number, and has no single value to add one to, so the run is rejected before any data is read.
How to fix
Take the highest sequence number, not the list, and add one to it:
- name: NEXTSEQ
type: int
derivation:
aggregate:
key: [STUDYID, USUBJID]
expr: "MAX(AE.AESEQ) + 1"
The order and the separator that the list needed go with it: the highest value reads neither.
