Gamma-glutamyltransferase, general and cause-specific mortality in 19,000 construction workers followed over 20 years

Background: Associations of serum gamma-glutamyltransferase levels (g-GT) with a variety of incident diseases and mortality have been suggested. The present study attempted to expand the body of evidence to especially relevant occupational cohorts in which exposure to established g-GT determinants may greatly differ from the general population.
