Impacts of common factors of life style on serum liver enzymes

Figure 2 Interactions of ethanol intake with age on alanine aminotransferase and gamma-glutamyltransferase levels in men. An aggravated effect of ethanol was seen in those who were over 40 years of age and consumed over 16 drinks of alcohol per week. In women, the interaction between alcohol use and age was not significant (Table 3). Smoking and coffee consumption were used as covariates. ALT: Alanine aminotransferase; GGT: Gamma-glutamyltransferase.
