Thanks Tom,
The GOLD initiative says "Who Are We? GOLD was launched in 1997 in
collaboration with the National Heart, Lung, and Blood Institute,
National Institutes of Health, USA, and the World Health Organization. "
but then if you go to the sponsors page there is a long list of
pharmaceutical companies. On a plus note, it does recommend pulmonary
rehabilitation but does not cite the Cochrane review. In fact, among its
447 references there is only one or the dozen or so Cochrane reviews
relevant to COPD.
Cheers
Paul
