It should also be noted that p-mTOR had an overtly reduced 1-year OS rate (RR = 1.86, 95%CI 1.50–2.31, P < 0.001, Fig. 7d); moreover, significant associations were found of p-mTOR overexpression with 3-year (RR = 1.71, 95%CI 1.52–1.93, P < 0.001, Fig. 7e) and 5-year (RR = 1.53, 95%CI: 1.26–1.86, P < 0.001, Fig. 7f) OS in GC patients. The gene discussed is MTOR; the disease is gastric cancer.
