4 Fig 3 Forest plot of overall long-term risk of developing valve-related morbidity, including major adverse prosthesis-related event (MAPE), anticoagulant-related events, major bleeding, reoperation, and structural valve degeneration (SVD), with bioprosthetic valve (BV) compared with mechanical valve (MV) after surgical aortic valve replacement.

5 Fig 4 Overall Kaplan-Meier survival curves based on reconstructed individual study data. (A) Aggregated survival curves for bioprosthetic valve (BV [blue line]) compared with mechanical valve (MV [red line]). (B) Long-term survival of the BV cohort after aortic valve replacement, reconstructed from 4,072 patients. (C) Long-term survival of the MV cohort after aortic valve replacement, reconstructed from 4,589 patients. (CI = confidence interval; HR = hazard ratio.)

6 Fig 5 Overall Kaplan-Meier survival curves based on reconstructed individual study data. Aggregated survival curves for bioprosthetic valve (blue lines) compared with mechanical valve (red lines) after aortic valve replacement in patients aged (A) 50 to 70 years; (B) 60 to 70 years; and (C) less than 65 years.

7 Fig 6 Overall Kaplan-Meier survival curves based on reconstructed individual study data. Aggregated survival curves for (A) bioprosthetic valve compared with (B) mechanical valve after aortic valve replacement in patients aged 50 to 70 years (green lines), 60 to 70 years (blue lines), and less than 65 years (red lines).
