Associations between BPV and patient demographics. OR patients (n = 15) were stratified by age, history of hypertension (HTN), and history of vascular disease (VD). BPV was assessed using three metrics: standard deviation (SD), coefficient of variation (COV), and average real variability (ARV). *signifies p < 0.05; ** signifies p < 0.01.
