Summary of the Proposed Research:

The analyses of this study will help to further build an understanding of the performance of different statistical methods for analysing randomised clinical trials where the outcome is the time until some event, e.g. cancer recurrence, death. We will apply currently available statistical methods to compare their statistical properties. Based on this investigation we will be able to make recommendations about which statistical methods are most appropriate to analyse such data. This will enable analyses to give a better description of how treatment effects change over time and may also enable trials to require fewer patients, leading to cost savings and new efficacious drugs being made available to patients faster.
