Table 3 Diet items that were differentially associated with toenail arsenic depending on household water arsenic

From: Diet and toenail arsenic concentrations in a New Hampshire population with arsenic-containing water

  1. Legend: Model results for the diet items for which the associations with ln-transformed toenail arsenic concentration, adjusted for tap water arsenic concentrations and potential confounders, depended on whether the household tap water arsenic concentration was above or below 1 μg/L. Sample sizes ranged from n = 627-648 for tap water arsenic <1 μg/L and n = 194-195 for tap water arsenic ≥ 1 μg/L.
  2. 1These columns summarize the percent change in predicted toenail arsenic concentration from 5th to 95th percentile consumers for males and for females; gender is included since males and females consumed some diet items (e.g., beer, wine) differently.
