The total number of individuals with hemodynamic measures is 39, which is 4 less than the total sample size (Table 1). There were 4 individuals with no apnea, hypopnea, or RERA events and therefore contributed no hemodynamic data. , number of patients; , number of hemodynamic events; SBP, systolic blood pressure; DBP, diastolic blood pressure; mmHg, millimeters of mercury; BPM, beats per minute; RERA, respiratory event related arousal; REM, rapid eye movement; GH, gestational hypertension; SD, standard deviation; .
