Prevalence of hyper-U-β₂M and hyper-U-NAG corresponding to U-Cd intervals among subjects from county A (CA) and county B (CB) at different cadmium exposure levels¹.

1<p>The 90^th percentiles of U-β₂M and U-NAG of the control group were assumed as the thresholds of hyper-U-β2M and hyper-U-NAG, respectively.</p>2<p>U-Cd intervals were divided according to the three corresponding quartiles (i.e., Q₁ = 2.38 µg/g cr_, Q₂ = 4.47 µg/g cr, and Q₃ = 8.59 µg/g cr in CA; and Q₁ = 1.16 µg/g cr_, Q₂ = 2.86 µg/g cr, and Q₃ = 6.88 µg/g cr in CB).</p><p>U-β2M, urinary level of β2-microglobulin; U-NAG, urinary level of N-acetyl-β-D-glucosaminidase; U-Cd, urinary level of cadmium.</p><p>Prevalence of hyper-U-β₂M and hyper-U-NAG corresponding to U-Cd intervals among subjects from county A (CA) and county B (CB) at different cadmium exposure levels^{<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0115794#nt119" target="_blank">1</a>}.
