MKI67 and gastric cancer: The pooled HRs from a random-effects model indicated that an elevated expression of Ki-67/MKI67 predicted a poor OS (HR: 1.54, 95% CI: 1.33-1.78, P<0.0001; I2=69.6, P<0.0001; Fig. 3a) and DFS (HR: 2.28, 95% CI: 1.43-3.64, P<0.0001; I2=65, P=0.014; Fig. 3b) in patients with gastric cancer.
