dbp_mean
Mean of seated diastolic pressures
Mean of seated diastolic pressures

Mean of two standard seated blood pressure measurements on the night of the PSG. If repeat measurements were taken, the mean of the closest two measurements.

sbp_mean
Mean of seated systolic measures
Mean of seated systolic measures

Mean of two standard seated blood pressure measurements on the night of the PSG. If repeat measurements were taken, the mean of the closest two measurements.

Clinical Data/Vital Signs
death_cause_1
Death cause #1
Death cause #1

Cause of death came from death certificates with an internal adjudication process to categorize cause of death into grouping for research purposes. Death certificate searches were completed on a regular basis. Due to delays in reporting of deaths and death searches, cause of death was not available for all known deaths; based on the last search, death year was available for deaths reported through 2017. (CVD = Cardiovascular Disease)
