The most recent such analysis was published last month and
suggested Avandia is more likely to cause strokes and heart
-related death than a rival drug, Actos, made by Japan-based Takeda Pharmaceuticals.
The paper's chief author, Dr. David Graham, an FDA scientist who wants the pill banned, estimated as many as 100,000 heart-related problems may have been caused by Avandia.
The study analyzed medical records of more than 225,000 elderly Medicare patients.
