  1. *Aspartate aminotransferase, Alanine aminotransferase, Gamma glutamyl transferase, §Trichloroethylene.
  2. p-values were tested by one-way ANOVA. and the post-hoc test was based on Duncan's method.
  3. p-values were tested by general linear model adjusted for age, body mass index, work duration, smoking, and alcohol intake by general linear model. The post-hoc test was based on Bonferroni's method.
  4. a,bThe same letters indicate a non-significant difference between groups.
