Review ask

As a clinical trial statistician or programmer, answer two short questions in Your review: the task and the inputs and outputs. 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.

What this benchmark means
README.md

Public entries: Python and R. Passing coverage requires an installed inventory.

Goal: one row per adverse event (AE) with an analysis end date (AENDT), and an analysis start date (ASTDT) completed from a partial start no earlier than first exposure and no later than the event's end, and a flag (ASTDTF) marking how much of the start date was supplied.

Input: one spec.yaml over adverse event records carrying the reported term (AETERM) and the collected start and end (AESTDTC, AEENDTC): a full date, a year and month, a year alone, or no end at all, plus the first exposure date (TRTSDT) from the subject-level analysis dataset (ADSL).

Variables:

  • TRTSDT is the subject's first exposure date.
  • ASTDT is the analysis start date. A fully collected start is used as it stands. A partial start takes the first day it allows, then moves up to TRTSDT and back to AENDT wherever either date falls inside the collected month or year; a date outside it moves nothing. When both fall inside and first exposure is the later, the start takes the end date, so a start is never placed after the event ended.
  • ASTDTF is D when the day was supplied and M when the month and day were supplied, whether or not first exposure or the end then moved the date. It is empty when the start was collected in full.
  • AENDT is the analysis end date: a fully collected end as it stands, a year and month completed to the last day of that month, and a year alone to 31 December; empty when no end was collected.

Note: when first exposure and the end both fall inside the collected period and cross, the end wins, so the start never follows the end it belongs to and is never left empty.
