GO enrichment terms of DE-circRNAs (whose host genes are DEGs). (A-D) The top 20 GO enrichment terms of DE-circRNAs (whose host genes are DEGs) that up-regulated and down-regulated in the fetus vs. child group (A-B) and fetus vs. adult group (C-D). There are four circles from outside to inside. The first circle is the classification of GO enrichment terms. Different colors represent different categories. The second circle represents P-value and the number of background genes in the category. The more genes, the longer the bar. The smaller the P-value, the redder the color. The third circle shows the total number of foreground genes. The fourth circle is the RichFactor value of each category (the number of foreground genes in the category divided by the number of background genes). Each grid of the background auxiliary line represents 0.1
