1, 2Cut-off values of U-β2M or U-NAG were defined as the 84th or 90th percentile values, which were calculated in subjects from Cd-non-polluted areas.3OR: Odds ratio.4CI: Confidence interval.5Explanatory variables were used as continuous variables.**PPCA, county A; CB, county B; U-β2M, urinary level of β2-microglobulin; U-NAG, urinary level of N-acetyl-β-D-glucosaminidase; U-Cd, urinary level of cadmium.Results of the logistic regression analysis on individual factors related to Cd-induced renal tubular damage.
