Footnote
▶CARE-LA data were weighted (a statistical method to adjust over-represented and under-represented demographic characteristics in a study sample) so that the summary results adequately reflect the population of California’s Los Angeles County. Unweighted results are available to download on the California Regional Exposure Study, Los Angeles County (CARE-LA) project page.
◘Butylparaben was tested among only 60 participants. The sample size is not sufficiently large enough to provide weighted summary statistics.
Summary Result Type
Weighted - Unweighted
