To provide a quantitative assessment of the association between excess bodyweight, expressed as increased body-mass index (BMI), and the risk of gallbladder cancer (GBC), we conducted an updated metaanalysis of epidemiologic studies. Methods: We searched the MEDLINE and EMBASE databases form1966 to February 2013, and the reference lists of retrieved articles. A random-effects model was used to combine study-specific results.
