Limitations and Caveats

This was not a prospective randomized clinical trial. Adverse events were not collected real time and were based on retrospective chart review. The number of deaths reported in the Adverse Events section is the total deaths during the study period for both arms while the adverse events were collected for only the surgical arm. The percentages differ with the rates reported in the Endpoint section since those rates are based on the Kaplan-Meier estimator
