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: fill SEVAL, the severity recorded at the visit, from
the collected severity when present, otherwise from SEVAL
itself, defaulting to 0 when neither gives a value.
Input: vital-sign records carrying study, subject, and sequence
entries plus the collected severity (SEVAL), which is missing
when no severity was recorded.
Variables:
SEVAL: the collected severity when one was recorded at the visit, otherwise the value ofSEVALitself, otherwise0. BecauseSEVALreads its own value, there is no earlier value to carry and the definition loops back on itself, so the run is rejected before any data is read and no artifact is accepted.
How to fix
Carry forward from the collected source instead of the column being
derived. Search the subject's earlier collected values in a separate column,
and fall back to it, then to 0, only when the current record has no
severity:
- name: SEVPREV
type: int
derivation:
locf:
source: VS.SEVAL
include_current: false
window:
group_by: [STUDYID, USUBJID]
order_by: [VSSEQ]
- name: SEVAL
type: int
derivation:
first_available:
sources: [VS.SEVAL, SEVPREV]
missing: 0
Keep SEVPREV internal by omitting it from output.columns. A subject whose
first record has no severity gets 0 there, because no earlier value exists.
