Difference between date of systolic and diastolic blood pressure measurements and sleep test

bp_offset under Clinical Data/Vital Signs/Seated Blood Pressure in NCHSDB variables

Derived using dates from the MEASUREMENT.CSV and SLEEP_STUDY.CSV data files.

Single measure of seated systolic blood pressure closest to the sleep test

bp_systolic under Clinical Data/Vital Signs/Seated Blood Pressure in NCHSDB variables

The NSRR team extracted values from the MEASUREMENT.CSV file and kept the value closest to the time of the sleep study. Reference: :bp_offset:
