Meta-analysis of differentially expressed genes involved in NSCLC by combining values. (a) Principal component analysis (PCA) biplot of quality control measures in thirteen NSCLC studies. (b) The number of differentially expressed genes plotted as a function of false discovery rate (FDR) in the analysis of four different datasets and four different meta-analysis algorithms (maxP, minP, roP, and adaptively weighted statistic). Figure 2 was reproduced from Sun et al. [16].
