At first, the univariate and multivariate Cox regression analyses were employed to decide the independent prognostic factors of the risk score from the five HRRlncRNAs, namely, age, disease stage, histological grade, tumor residual size, BRCA1/2 mutations, and MKI67 in EOC; the results demonstrated that the risk score of the model was the independent prognostic factor for EOC patients (p < 0.001, HR = 1.295, and 95% CI = 1.149–1.459; Figure 5A; and p < 0.001, HR = 1.326, and 95% CI = 1.150–1.529; Figure 5B). The gene discussed is BRCA1; the disease is neoplasm.
