Chondroitin Sulfate not good for arthritis relief?

Chondroitin Sulfate is used by many people I know for achy and arthritic joints -- but does it actually work? A recent clinical analysis says that it doesn't; in fact, chondroitin and sugar pills have the same effect.

I'm not sure I'm ready to believe this at all without knowing who is behind the clinical analysis (which is hugely important) or determining if there is any influence at work here to discredit a natural alternative (we've seen it before, folks). But, are you willing to no longer use your chondroitin supplements for those painful joints?

So, does the "better data" cited in this analysis hold water? From outward appearances, it looks like it does. Without more detail, I'm not throwing my opinion yet, however.
