Heat map and volcano map of differential genes of Normal and PCOS patients with GSE1615 chip. A Volcano map. The X-axis was log2 (fold change). The Y-axis was -log10 (Pvalue). B We selected the top 20 differentially expressed genes for the heat map (blue is a low expression, yellow is a medium expression, and red is a high expression). All genes were first set as undifferentiated genes (denoted in Grey) and screened according to the logFC and adjusted p-value. When the adjusted p-value was < 0.05 and the logFC ≥ 1, it was noted as an upregulated gene (shown in red); when the adjusted p-value was < 0.05 and the logFC ≤ -1, it was noted as a downregulated gene (shown in blue)
