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: derive each subject's date of first exposure to treatment
(TRTSDT) from the subject's earliest exposure record.
Input: demographics records, and exposure records carrying the start
date of each administration (EXSTDTC).
Variables:
TRTSDTwould be the start date of the subject's earliest exposure record, and blank for a subject with no exposure record.
Note: exposure records are matched to a subject by listing the columns the two must share, and the list names the subject identifier twice. A repeated column states the same match again and may hide a column that was meant instead, so the run is rejected before any data is read and no artifact is accepted.
How to fix
Name each matching column once. When the repeated entry was meant to be a different column, name that column instead:
intermediates:
- id: FIRSTDOSE
dataset: EX
key: [STUDYID, USUBJID]
order_by: [EX.EXSTDTC]
keep: first
