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.

Summary

Lifecycle: draftEditUnder review
What this benchmark means
README.md

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

Goal: carry the demographics identifiers and collected values with Define-XML 2.0.0 metadata and a SAS transport file; DOMAIN holds DM.

Input: project.yaml selects Define-XML 2.0.0 and composes spec.yaml, which maps demographic capture records from input/dm_raw.csv into the demographics table and supplies its submission metadata.

Variables:

  • SUBJID is the subject identifier within the study.
  • RFSTDTC is the subject's reference start date, blank when unavailable.
  • SITEID identifies the site.
  • AGE is the collected age, with AGEU fixed to YEARS.
  • SEX, RACE and COUNTRY retain the recorded values.

Note: the submission uses the older metadata representation: its guide is recorded on the metadata version, its dataset class is an attribute, and collected origins are marked CRF. The dataset values and transport layout are the same as in the corresponding newer-format submission.
