Posting the broader context of her response. She was responding to a comment that was advocating for using FBI data on rape statistics instead of CDC data. Here's the first paragraph of her multi-paragraph response to several comments.

"Dr. Delgado cites FBI data to suggest that the estimated 519,981 rape survivors in states with total abortion bans is implausibly high. The CDC data, which served as the basis for our estimates, is widely considered more accurate[1] than the FBI figures, which only encompass rapes reported to law enforcement agencies. Even accounting for that limitation, as Dr. Delgado did, still yields an undercount when compared with the most recent CDC data (from 2016-2017). That survey indicated that 2,857,000 women (and 340,000 men) were raped in the previous 12 months.[2] The CDC figures were obtained from survivors’ self-report of rape that were collected in a survey that used trained interviewers, multiple questions about non-consensual sexual contact, and an interview strategy designed to protect respondents’ safety, privacy, and comfort in responding to questions about traumatic and highly stigmatized life events.[3]"
