Old abstracts in no way make the evidence any more refutable. It just means that this has been established 15 years ago, yet people still try to state the opposite as fact.
Yes, it does. Research changes over time. So what you are saying is that asbestos does not cause cancer? What about DDT? That's healthy to so go ahead and cover your garden with large amounts of it. New studies impact old ones day in and day out. To say that old abstracts done on studies that are 15-20 years old are the best evidence out there is bad info. Ask pain-main.
Hey, Pain-main. Do you ascribe to all the old med journals out there and old AMA data when there is new data?
Now, I'm not saying that all old data is bad data - but I'm pretty certain that if you wanted to make your argument better you need to look at newer research.
