Abstract

Since the early 1990s, motivated by the availability of patient-level cost data in clinical studies for comparing patient groups, researchers have made rapid developments in statistical methods for cost-effectiveness data. Initial efforts concentrated on inference about the incremental cost-effectiveness ratio, but due to difficulties associated with ratio statistics, interest has settled more recently on incremental net benefit. Regardless of the approach, five parameters need to be estimated: the between-treatment ...
