1. Comparison between Kaplan-Meier survival estimates of Bristol aortic valve surgery patients and the Monte Carlo-based generated Kaplan-Meier curve using the matched ONS population.
Comparison between Kaplan-Meier survival estimates of Bristol aortic valve surgery patients and the Monte Carlo-based generated Kaplan-Meier curve using the matched ONS population. It appears that for a follow-up period of <8 years, the difference between the survival estimates is not significant (p=0.55) using log-rank test for equality of survivor functions. However, for longer periods of follow-up, the difference becomes increasingly significant with p< for the entire follow-up period. ONS, Office for National Statistics.
