Feigelson and colleagues have raised some important points concerning the selection of the data sets and the application of meta-analysis to resolve some of the problems associated with determining the relationships between metabolic polymorphisms and susceptibility to various disease conditions. In recent years, many meta-analyses have been published with the aim of providing more objective and quantitative summaries of genetic association studies (Lau et al., 1998
; Dunning et al., 1999
; de Jong et al., 2001). However, there are always concerns that combining studies with different
