MDM2 and cervical cancer: The association between MDM2 rs2279744 polymorphism and cervical cancer susceptibility in homozygote model was assayed using data from 8 studies, and we found that MDM2 rs2279744 polymorphism in homozygote model was significantly related to high cervical cancer susceptibility (OR = 1.469, 95% CI: 1.031-2.095, P = 0.033; 95% PI: 0.516-4.184), however, heterogeneity was found to be relatively large (I2 = 65.7%, Tau2 = 0.1502) (Figure 2D).
