Researchers are calling for the retraction of misleading anti-abortion studies that could influence judges in critical cases

The retraction of three peer-reviewed articles prominently cited in court cases on the so-called abortion pill – mifepristone – has put a group of papers by anti-abortion researchers in the scientific limelight.

Seventeen sexual and reproductive health researchers are calling for four peer-reviewed studies by anti-abortion researchers to be retracted or amended. The papers, critics contend, are “fatally flawed” and muddy the scientific consensus for courts and lawmakers who lack the scientific training to understand their methodological flaws.

While some papers date back to 2002, the group argues that now – in the post-Roe v Wade era – the stakes have never been higher. State and federal courts now routinely field cases on near-total abortion bans, attacks on in vitro fertilization and attempts to give fetuses the rights of people.

“When we saw the meta-analysis presented again and again and again – in the briefs to the Dobbs case” that overturned Roe v Wade “and state cases” to restrict abortion, “the concerns really rose,” said Julia Littell, a retired Bryn Mawr professor and social researcher with expertise in statistical analysis.

A meta-analysis is a kind of research that uses statistical methods to combine studies on the same topic. Researchers sometimes use these analyses to examine the scientific consensus on a subject.
