More than 5000 suits have been filed; Wyeth has now won both federal trials (Sep. 17), and lost a state trial in Pennsylvania where the judge overturned a punitive damages award. [AP/Law.com]

Interestingly, the plaintiffs appear to be hanging their case on a study allegedly showing a relative risk of 1.24 for Prempro (Wyeth claims the relative risk is smaller).
