Avandia has come under the microscope in the last month as the Cleveland Clinic attributed the diabetes drug to heart problems. As usual (it seems), there is another party that is refuting that evidence and is saying that there is no significant increase in heart attacks by patients using Avandia.

This time, the British study -- which was funded by a"drug company" -- stated that there was no connection between Avandia use and heart attacks. If the "drug company" was Avandia maker GlaxoSmithKline, is the new study to be believed at all?

Without total and complete transparency here, I would not put much stock on a new study unless conducted without bias by an independent lab/researcher. Just my two cents.
