A summary of all the studies and data sets used for the meta-analysis. Each study is defined by the name of the first author. Where possible, the number of differentially expressed (DE) that were enriched (more prevalent) or depleted (less prevalent) reported in the study for each data set is given, along with the corresponding number of DE genes that were calculated using the independent analysis of the raw data in this report (genes observed). In cases where the reporting authors did not differentiate between up and downregulated genes (just the total number of DE genes were reported), we have designated this a “total” DE genes reported in the upregulated column.
