Table 5 Effect of chromium concentration in erythrocytes on, Urinary 8-OHdG, Olive tail moment, Tail Length and Tail DNA%.

dependent variables*	95%CI^#	Pvalue	r^{2 §}
urinary 8-OHdG	0.146 (-0.171,1.163)	0.143	0.157
Olive tail moment	0.445 (0.357,0.847)	<0.001	0.336
Tail Length	0.387(0.356,1.031)	<0.001	0.206
Tail DNA%	0.352(0.178,0.618)	0.001	0.154

* In the multivariate linear model, chromium concentration in erythrocytes, gender, age, smoking status, alcohol consumption were independent variables and Olive tail moment, Tail Length, Tail DNA% and urinary 8-OHdG were dependent variables, respectively. The raw data of dependent variables (Olive tail moment, Tail Length, Tail DNA% and Urinary 8-OHdG) were transformed with square-root.
^# the coefficient of linear regression.
^§ r², the decisive coefficient in the equation.
