5. Figure 4
Multivariate logistic regression analysis for preoperative predictors of reduction in mean PAP. According to the reduction of mean PAP, the entire study population was divided into 2 groups: responders (patients with ≥ 10 mm Hg reduction after AVR) and nonresponders (patients with < 10 mm Hg reduction after AVR).
