Summary
EditUnder reviewWhat this benchmark meansREADME.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: combine blood pressure measured at clinic visits with blood pressure
measured at home, with the study day in VSDY, where the blood pressure was
measured in VSCAT, and the systolic blood pressure in VSSTRESN: one record
per clinic measurement, and one record per subject and day of home readings.
Input: clinic measurements, one per visit, and home readings, of which a
subject may take several on one day. Both carry the study day (VSDY) and the
systolic blood pressure (SYSBP).
Variables:
VSCATwould beCLINICfor a clinic measurement andHOMEfor a day of home readings.VSSTRESNwould be the systolic blood pressure: the measurement itself on a clinic record, and on a home record one value standing for all of the day's readings.
Note: each home record stands for all of the subject's readings on that day, so a single reading's blood pressure is not a value of that record: a day with several readings has several such values. The home record's blood pressure is taken from a single reading, so the run is rejected before any data is read and no artifact is accepted.
How to fix
Decide which value stands for a day of home readings. Usually it is the mean of the day's readings, so average them on the home record:
VSSTRESN:
aggregate: "MEAN(HOME.SYSBP)"
To keep every reading instead, build one home record per reading, without grouping the readings by day, and add a key that tells one day's readings apart, such as the time each reading was taken.
