Univariate Cox regression model analysis showed that distant metastasis (P = 0.003), TNM stage (P = 0.000) and lncRNA HAGLORS expression level (P = 0.002) were strongly associated with poor prognosis in breast cancer patients, and multivariate Cox regression model analysis showed that lncRNA HAGLROS expression level (P = 0.048) was an independent prognostic risk factor for patients (Supplementary Table 6). The gene discussed is HAGLROS; the disease is breast cancer.
