Table 2 Factors associated with urine mercury levels

From: The association between amalgam dental surfaces and urinary mercury levels in a sample of Albertans, a prevalence study

  Unprovoked mercury (μg/g-creatinine) Provoked mercury (μg/g-creatinine)
  Effect 95% CI P Effect 95% CI P
Baseline Level 0. 470 μg/g 0.314, 0.627 <0.001 1.73 μg/g 0.657, 2.806 <0.001
Per Surface 0.04 μg/g 0.03, 0.04 <0.001 0.32 μg/g 0.28, 0.35 <0.001
< 74 kg* 0.30 μg/g 0.10, 0.49 0.002 3.41 μg/g 2.11, 4.73 <0.001
74 to 90 kg* 0.15 μg/g −0.04, 0.34 0.118 1.69 μg/g 0.40, 2.97 0.015
Female vs Male 0.52 μg/g 0.31, 0.63 <0.001 4.14 μg/g 3.04, 5.24 <0.001
  1. * baseline group: >90 kg. Other than the baseline level, the effect indicates the unit increase in mercury level associated with each participant characteristic.
