The heatmap of the subset 407 DEGs identified in the meta-analysis. For each DEG, its normalized expression value in each sample of the nine datasets was indicated in the heatmap. Two hundred forty one genes were up-regulated and 166 genes were down-regulated. The genes were clustered using the Ward’s method [56]. The samples were grouped first by comparison group then by individual studies
