  1. * The raw data of dependent variables (Cr (VI) in erythrocytes, Tail Length, Tail DNA%, Olive tail moment and urinary 8-OHdG) were transformed with square-root.
  2. ** Chromium exposure was quantified as 1 = exposed, 0 = un-exposed.
  3. # the linear regression coefficient.
  4. § r2, the decisive coefficient in the equation.
  5. ∫ Adjusted factors were defined as gender: 0 = male and 1 = female; age: 0 =< 30, 1 = 30-40, 2 => 40; smoking status: 0 = no, 1 = yes; alcohol consumption, 0 = no, 1 = yes
