5. Fig 4
Linearized rates of thromboembolism (A) and stroke (B). Risks of thromboembolism were higher for patients in the Silzone group compared with the non-Silzone valve, but these differences were largely due to transient events because the risks of stroke were low.

6. Fig 5
Analysis of cumulative hazard of major paravalvular leak suggests a constant risk of 4.6% during the first 2 years after the operation. (CI = confidence interval; Postop = postoperative.)
