STAT2 mRNA level showed a null association with OS amongst all the ovarian cancer patients, HR =1.00 (0.80−1.26), P=0.97 (Figure 2A), serous ovarian cancer patients, HR =1.04 (0.81−1.34), P=0.74 (Figure 2B), as well as endometrioid ovarian cancer patients, HR =2.92 (0.30−28.15), P=0.33 (Figure 2C). The gene discussed is STAT2; the disease is ovarian serous adenocarcinoma.
