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: read the analysis start of each concomitant medication as ISO 8601
text (ASTDTC) and as a date (ASTDT) from the collected start
(CMSTDAT).
Input: concomitant medication records, each identified by its sequence
number (CMSEQ), carrying the collected start as the site wrote it.
Variables:
ASTDTCwould be the start as ISO 8601 text, read from an ISO 8601 date or from a two-digit day, three-letter month and four-digit year such as04MAR2001. A start written in any other spelling has no stated reading, so the run stops when it reaches one and no artifact is accepted.ASTDTwould be the analysis start date, a month alone completed to its first day.
Note: a start that was never collected and a start in an unlisted spelling are different defects: the first gives no analysis start, while the second has no stated reading here.
How to fix
Correct the collected start upstream when the intended date is clear:
4 March 2001 recorded as 04MAR2001 reads as March 4, 2001. Declare a
spelling instead only when the sites use it and one of the closed date forms
reads it. The list names each spelling the sites use, with at most one of
the two slashed orders, so a study whose sites also write slashed dates
month first declares:
derivation:
date_text:
source: CM.CMSTDAT
forms: [iso, ddmonyyyy, mdy_slash]
No form reads 4 March 2001 itself. If text in an unlisted spelling is
intentionally treated as no analysis start, declare that outcome locally
with invalid: null.
