Plotted for each dataset are empirical cumulative distributions of p values for upregulated miRNAs (turquoise) and downregulated miRNAs (orange), with the respective cumulative distributions of the fitted BBUM model overlaid as smooth lines. The uniform null distribution is shown as a gray dashed line. Deviation between the distribution for downregulated miRNAs and the null distribution is shaded in light orange; a greater deviation at the lower tail indicates a greater excess in density near p = 0, which corresponds to a more substantial contribution of the beta component for secondary effects in the BBUM modelBack to article page
