The record
In the OCWAA consortium's population-attributable-risk analysis, African American women had a higher PAR than White women for modifiable exposures including body powder: 36.0% (95% CI 21.0%-48.8%) versus 13.8% (95% CI 4.5%-21.8%), FDR P = .04.
Claim scope
THIS IS THE CORRECT CITATION FOR THE DIFFERENTIAL-BURDEN CLAIM. Verified per-record: J Natl Cancer Inst 2021;113(6):710-718, DOI 10.1093/jnci/djaa188. It quantifies, with confidence intervals and multiple-testing correction, that a larger fraction of ovarian cancer among African American women is attributable to modifiable exposures. This is the statistically correct way to express a differential burden without misstating the risk ratio.
What this source does not establish
The 36.0% PAR is for a GROUP of four exposures — body mass index, oral contraceptives, aspirin, AND body powder — not for body powder alone. The page must NOT write '36% of ovarian cancer in Black women is attributable to talc.' That would be a serious misstatement.
Limitations
Cite this for the burden concept and always name all four exposures in the grouping. If the page needs a powder-only PAR, PMID 25873577 reports talc-specific PAR% of 12.2%-15.1% across three racial/ethnic groups — see the next finding.
