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: one row per adverse event (AE) with its analysis start date
(ASTDT) and the study day of that start (ASTDY).
Input: collected adverse events with the onset date (AESTDTC) and the
subject's first treatment date (TRTSDT).
Variables:
ASTDTis the onset date as collected.TRTSDTis the date of the first exposure to treatment.ASTDYwould be the study day of the onset: the first treatment date is day 1 and the day before it is day -1. A study day is a count of days, and the column meant to hold it holds calendar dates, so the run is rejected before any data is read and no artifact is accepted.
How to fix
Store the study day as an integer, the type every study day has:
- name: ASTDY
type: int
label: Analysis Start Relative Day
derivation:
study_day:
source: ASTDT
reference: TRTSDT
A specification that needs the calendar date of the onset already has it in
ASTDT.
