Abstract
We consider the analysis of data from the MRC Multicentre Trial for Early Epilepsy and
Single Seizures (MESS), which was undertaken to assess the differences between two policies: immediate, or deferred treatment in patients with single seizures or early epilepsy.
In studies of recurrent events, like epileptic seizures, there is typically lots of information
about individuals' seizure patterns over a period of time, which is often not fully utilised
in analysis. We develop methodology that allows pre-randomisation seizure counts and
multiple post-randomisation survival times to be jointly modelled, assuming that both
these outcomes are predicted by (unobserved) seizure rates. The joint model was found to
be superior to standard survival methods, although interesting characteristics within the
data, not present in the model were also highlighted. We consider modifications to the
joint model to accommodate these properties.
