Application of Mendelian randomization in liver cancer / 临床肝胆病杂志

In recent years， the research method of Mendelian randomization based on genome-wide association studies has been widely used for etiological exploration in the medical field， which can effectively overcome the confounding biases and interference of reverse causalities in traditional observational researches with its unique advantages of the distributive randomness and timing priority of genetic variants. This article reviews the method of Mendelian randomization and its application in liver cancer， in order to provide new ideas for the research on causal association in liver cancer.
