Comparison of power. Power comparison for the different methods. The x-axis denotes the 8 categories of genes, categorized by the number of studies that the genes are differentially expressed in. There are 1650 genes in the category 0 (no differential expression in any studies). The rest of the categories contain 50 genes each. For each category, the proportion of genes found significant within that category are plotted for each method.
