yamaa As a clinical trial statistician or programmer, answer two short questions in Your review: the task and the inputs. 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: combine blood pressure measurements taken at the clinic and at
home, with the study day in VSDY, where the measurement was taken in
VSCAT, the systolic blood pressure in VSSTRESN, and how often the device
used was calibrated in NCAL.
Input: clinic measurements carrying the study day (VSDY), the systolic
blood pressure (SYSBP) and the device number (DEVICEID), home
measurements carrying the study day and the systolic blood pressure, and the
calibration records of each device (CALDY, the day of a calibration).
Variables:
VSCATwould beCLINICorHOME.VSSTRESNwould be the systolic blood pressure.NCALwould be the number of calibration records of the device the measurement was taken with.
Note: every record's calibration count is matched on the clinic measurement's device number. The home measurements build some of the records, and a home measurement has no clinic measurement of its own, so the run is rejected before any data is read and no artifact is accepted.
How to fix
Carry the device number on each record, blank for the home measurements, which name no device, and count the calibrations of that value:
- name: DEVICEID
type: str
label: Device Identifier
NCAL:
aggregate:
expr: "COUNT(CALIB.CALDY)"
key: {DEVICEID: DEVICEID}
The clinic template derives DEVICEID: CLINIC.DEVICEID and the home template
DEVICEID: null. A home record then matches no calibration and its count is
blank.
