The association between fasting blood glucose and the risk of primary liver cancer in Chinese males: a population-based prospective study

Background: To investigate the association between fasting blood glucose (FBG) levels and the risk of incident primary liver cancer (PLC) in Chinese males, a large prospective cohort was performed in the current study. Methods: A total of 109 169 males participating in the routine checkups every two years were recruited in the Kailuan male cohort study since May 2006. Cox proportional hazards regression models and restricted cubic spline (RCS) were used to evaluate the association between levels of baseline FBG and the risk of incident PLC. Results: Compared to the males with normal FBG (3.9⩽FBG
