yamaa 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
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) and date of death (DTHDT), each left blank when the subject has
no record to read it from.
Input: one spec.yaml over demographics, exposure records carrying each
administration's start date and dose, and disposition records carrying the
disposition event and its date.
Variables:
TRTSDTis the start date of the subject's earliest administration with a dose above zero; a subject whose administrations all have a zero dose, or who has none, has no first exposure date.DTHDTis the date of the subject's death disposition record; a subject with no death record has no date of death.
Note: a subject without a record to read is kept, with the date blank, instead of stopping the run, and each such blank is counted so the run reports how often it happened.
