hovered around significanceP=0.415
The meta-analyses suggested that the correlation between ANGPT2 mRNA expression and TNM stage of ADC hovered around significance (OR=1.44, 95% CI: 0.96-2.14, P=0.415, and I 2 =1.3%) (Figure 4 E) and there was no statistical difference of the ANGPT2 mRNA between the big tumor size (T 3 -T 4 ) and small tumor size (T 1 -T 2 ) (OR=1.17, 95% CI: 0.74-1.86, P=0.226, and I 2 =27.8%) (Figure 4 G) in ADC.
