Figure 2. Density Plot of Fetal Effect by Gene Set and Wilcoxon signed-rank test.
The density of each gene set’s fetal effect compared to the fetal effect of the whole genome. The x-axis is the fetal effect, or regression coefficient (pre-natal vs post-natal) and y-axis is the density. Black line indicates the genome and colored line indicates the gene set. Red line indicates significant increase, Purple line indicates significant decrease. Blue line is default, no significant difference in fetal effect of gene set compared to the transcriptome. One-sided p-values are shown for Wilcoxon signed-rank test for each gene set, elevation in the positive direction on the upper right side, and decrease in the negative direction on the upper left side.
