Applying Gene Ontology on specific genes to identify potential markers for NA PCOS. A Barplot showing the top 20 DAVID biological process analysis terms within the NA PCOS specific genes. Immunity terms and immunity related terms were labeled red and green, and other terms were labeled as blue. B Pie plot illustrating the percentage of immunity terms, immunity-related terms and other terms within the top 20 DAVID biological process analysis terms. C Venn plot showing number of NA PCOS specific genes on all immunity terms (> 5 frequency and with STRING connection) and top 20 immunity terms (> 2 frequency and with STRING connection). D Barplot illustrating the text co-occurrence number with PCOS for each candidate gene. E The GO terms with at least two candidate genes were listed (y-axis) and used to calculate text co-occurrence number with PCOS (x-axis). The most co-occurred term was labeled red. F The candidate genes within cytokine term were collected and performed with protein–protein interaction analysis by STRING analysis
