Abstract:
|
It is important to assess drug safety by comparing the incidence of adverse events between two treatment arms in clinical studies. Meta-analysis has been found to be useful by combining multiple studies involving the same adverse event. When the events are rare, most standard meta-analysis methods are problematic as estimation of sparse data are often biased. We propose a Bayesian hierarchical model for meta-analysis of rare binary adverse event data. We show the estimates of the treatment effect and the between-study heterogeneity parameter from the Bayesian method are less biased than the traditional moment based methods. We further develop testing procedures based on a Bayesian model selection approach.
