A, Changes in the mean SBP (mm Hg) among participants with baseline EBP versus without baseline EBP. B, Changes in the mean DBP (mm Hg) among participants with baseline EBP versus without baseline EBP. Linear mixed modeling was used to evaluate associations of baseline presence of EBP with postoperative SBP and DBP values adjusted for age at surgery, sex, race, surgical procedure, clinical center, and BMI. * P < .05 versus previous time point.
