Further, a risk model consisting of five genes (UBD, ISG20, CXCL11, HLA‐DOB, and ATP1A3) was constructed using least absolute shrinkage and selection operator regression and could predict the survival and prognosis of patients with ovarian cancer, while also revealing the immune microenvironment to a certain extent.21 The gene discussed is CXCL11; the disease is ovarian cancer.
