Figure 2From: Confounders in the assessment of the renal effects associated with low-level urinary cadmium: an analysis in industrial workers Associations between urinary RBP and the concentrations of Cd in urine or blood in workers stratified in never, ever and current smokers. Concentrations of Cd in urine, expressed per g of creatinine, have been further adjusted for the residual influence of diuresis on the basis of the simple regression coefficient between log U-Cd and log urinary creatinine.Back to article page
