Footnote
◀CARE-2 data from 358 participants were weighted, a statistical method to adjust over-represented and under-represented samples, so that the summary results adequately reflect the population of California’s Riverside, San Bernardino, Imperial, Mono, and Inyo counties. Unweighted results are available to download on the California Regional Exposure Study, Region 2 (CARE-2) project page.
