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: carry the numeric result (LBSTRESN) and the baseline
flag (LBBLFL) as collected, and repeat the baseline value (BAVL)
on every row for the subject.
Input: collected lab (LB) records, each with a numeric result
(LBSTRESN) and a baseline flag (LBBLFL) holding Y on the
baseline record.
Variables:
BAVL: the baseline value, taken from the subject's row flaggedYinLBBLFLand repeated on every row for that subject; missing when the subject has no flagged row.
Note: the run is rejected when a subject has more than one
record flagged Y: no single baseline value exists, so no artifact
is accepted.
How to fix
Keep exactly one baseline record per subject. Either clear the flag in the
collected data on the visit that is not the baseline, for example WEEK 1:
STUDYID,USUBJID,VISIT,LBSTRESN,LBBLFL
PILOT7,P7-901,SCREENING,5.1,Y
PILOT7,P7-901,WEEK 1,5.4,
PILOT7,P7-901,WEEK 2,5.2,
or, when both visits genuinely qualify, pick one by rule (for example the earliest) and flag only that row before deriving.
