 Detailed legend: Univariate modeling of associations between endstage renal disease and erythrocyte metal concentrations, body mass index (BMI), diabetes, hypertension and smoking at baseline. For continuous variables, ORs are given for both unit increase and for an interquartile range increase.
 OR=odds ratio per unit increase. CI=confidence interval. IQR= interquartile range. OR_{IQR}=odds ratio for an interquartile range increase. BMI=Body Mass Index.

^{a}Hypertension was defined as SBP >140 or DBP > 90 mm Hg, or antihypertensive medication at baseline.
