review and statistical considerations for microarray meta-
analysis   With the rapid advances of various high-throughput
technologies, generation of ‘-omics’ data is commonplace in
almost every biomedical field. Effective data management and
analytical approaches are essential to fully decipher the
biological knowledge contained in the tremendous amount of
experimental data. Meta-analysis, a set of statistical tools for
combining multiple studies of a related hypothesis, has become
popular in genomic research. Here, we perform a systematic
search from PubMed and manual collection to obtain 620 genomic
meta-analysis papers, of which 333 microarray meta-analysis
papers are summarized as the basis of this paper and the other
249 GWAS meta-analysis papers are discussed in the next
companion paper. The review in the present paper foc
