Studies cited in case over abortion pill are retracted due to flaws and conflicts of interest

A medical journal has retracted two studies claiming to show the harms of the abortion pill mifepristone, citing conflicts of interest by the authors and flaws in their research.

Two of the three studies retracted by medical publisher Sage Perspectives were cited in a pivotal Texas court ruling that has threatened access to the pill. The U.S. Supreme Court will take up the case next month, with a decision expected later this year. The court's ruling could impact nationwide access to mifepristone, including whether it continues to be available by mail.

Medication abortion accounts for more than half of all abortions in the U.S., and typically involves two drugs: mifepristone and misoprostol.
