Abstract
Objectives: Time-to-event data, such as time to death or time to first seizure, are commonly used outcomes in medical research to summarise the length of time taken for a particular event of interest to occur. This workshop will discuss how to undertake a meta-analysis of time-to-event data.
Description: Methods for analysis of time-to-event data need to account for both the time to event and any related but unobserved events. Meta-analysis of time-to-event outcomes can be undertaken using data extracted from trial reports using a variety of different methods including an alternative more resource-intensive approach which involves a re-analysis of individual participant data.
