Figure 4. Intra-cluster correlations for baseline total hair mercury levels for households by community.
Intra-cluster correlations (95% CI) in total hair mercury levels for households in each community at baseline in unadjusted models (red) and models adjusted for age, sex, and asset index (blue) or age, sex, and occupation (green). Data shown only for communities with at least 20 households. Communities are ordered by location around the reserve, beginning with Queros (bottom left on map in Figure 1) and ending with Quincemil (bottom right on map in Figure 1.)
