Figure 2. Kaplan-Meier curves. A: following PSM, MPA embolism and non-MPA embolism patients were compared (log-rank test=5.23, P=0.022); B: following PSM and exclusion of saddle MPA embolism patients, non-saddle MPA embolism and non-MPA embolism patients were compared (log-rank test=4.70, P=0.030); C: following PSM, saddle MPA embolism and non-saddle MPA embolism patients are compared (log-rank test=1.20, P=0.729); D: following PSM, saddle MPA embolism and non-MPA embolism patients were compared (log-rank test=3.17, P=0.077); MPA: main pulmonary artery; PSM: propensity score matching.
