Visual overview of GMR for NHANES environmental biomonitoring data for all subgroups. Each cell of the matrix summarizes the outcome of the geometric mean ratio (GMR) test performed. The key to the color codes is located under the matrix. The columns correspond to the five race/ethnicity subgroups (Mexican American/High Income; Mexican American/Low Income; non-Hispanic black/High Income; non-Hispanic black/Low Income; non-Hispanic white/Low Income) that are being compared to the reference subgroup (non-Hispanic white/High Income). The rows of the matrix correspond to 410 studied biomarkers. The chemical groups to which these biomarkers belong (cotinine; halogenated aromatics; metals; polycyclic aromatic hydrocarbons, PAHs; polyfluoralkyl chemicals, PFCs; perchlorate; pesticides; phenols; phthalates; volatile organic compounds, VOCs) are indicated along the right edge of the matrix.
