The histograms of DE genes detected by the 7 meta-analysis methods. The DSLD2 method is proposed in this paper. Genes 1 to 200 are differentially expressed in only one study; genes 201 to 400 are differentially expressed in two studies; genes 401 to 600 are differentially expressed in three studies; genes 601 to 800 are differentially expressed in four studies; genes 801 to 1000 are differentially expressed in all studies; and genes 1001 to 2000 are not differentially expressed in any studies
