As happens all too often, causation and association have been confused: the headline of this article and the quote by the author imply causation, suggesting that lowering uric acid will improve longevity. But a study of this type cannot make such a conclusion. These are associated observations (which might or might not be causally linked). Similarly, it is potentially misleading to tell patients they'll live longer by improving compliance with urate-lowering therapy (as well-meaning as that might be).
