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 SEX and AGE for one record per subject, each from the
one record that holds the subject's answer.
Input: long-form Operational Data Model (ODM) data with one row per
collected item, carrying the visit (StudyEventOID), the form, the item
(ItemOID), and the stored value (Value).
Variables:
SEXis the sex answered at screening. A subject who is asked again at a later visit keeps the screening answer.AGEis the age collected for the subject; a subject with no age record keeps a missing age.
Note: an answer is read only when exactly one record holds it, so two records of one question at one visit stop the run even when they agree. Items the record does not read, such as a weight, play no part.
