  1. OR, odds ratio; 95% CI, 95% confidence interval; NAG, N-acetyl-glucosaminidase, β2-MG, Beta-2 microglobulin; eGFR, estimated glomerular filtration rate.
  2. Criteria for NAG is above 11.5 U/L; for β2-MG is above 300 μg/L; for eGFR is below 60 ml/min/1.73 m2.
  3. [Note] The variables in the first column are renal function indicators adjusted for gender, age, period of residence, body mass index; heavy metal concentrations were log transformed.
