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: show that numbering each subject's collected measurements
(VSSEQ) makes every measurement its own record, so the collection date
(VSDTC) it takes is the date collected beside that measurement, in the
same group of collected items.
Input: one spec.yaml over collected study data in operational data
model form (input/odm.csv: one record per collected item, with the item's
identifier, value and position in the study, event, form and item group).
Each vital signs item group holds a collection date and one or two blood
pressure measurements.
Variables:
VSSEQnumbers each subject's blood pressure measurements from 1 by item group; measurements of one group keep their collected order.VSTESTCDis the test,SYSBPorDIABP, taken from the item's identifier.VSORRESis the measurement as collected.VSDTCis the date collected in the measurement's own item group, and blank when that group has no date.
Note: only the blood pressure items become records. A record's date is looked up among all collected items, so the date item of its group is found although it is not a record itself, and the second group of a subject has its own date.
