Joint effects of coffee consumption and serum gamma‐glutamyltransferase on the risk of liver cancer
Gang Hu, Jaakko Tuomilehto, Eero Pukkala, Timo Hakulinen, Riitta Antikainen, Erkki Vartiainen, Pekka Jousilahti – 20 June 2008 – Only three Japanese prospective studies have suggested an inverse association between coffee drinking and liver cancer risk. No prospective studies on the association between serum gamma‐glutamyltransferase (GGT) and liver cancer risk have been reported. We aimed to determine the single and joint associations of coffee consumption and serum GGT with the risk of primary liver cancer.
