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
README.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: give each dose of study drug its analysis start date (ASTDT) and
the number of the subject's treatment period (APERIOD) whose days hold that
date.
Input: one spec.yaml over exposure records, each carrying a sequence
number (EXSEQ), the dose given (EXDOSE) and a start date (EXSTDT), and a
period table giving each subject's treatment periods, each from a first day
(APERSDT) to a last day (APEREDT).
Variables:
ASEQis the sequence number of the exposure record that gave the dose.ASTDTis the start date of the dose.APERIODis the number of the subject's period whose first and last days, both inclusive, holdASTDT. It is blank when none of the subject's periods holds the date.
Note: the analysis start date is stated once for the whole dataset, not in the rule that builds the dose rows, and only exposure records that gave a dose build rows. Each dose row still works out its own start date before its period is chosen, so the period always follows the date the output carries. A dose outside every period is kept with the period blank, and each such blank is counted so the run reports how often it happened.
