Cochrane Library online

[RichardR]

The British Government has arranged for everyone in the UK (ie, with a UK based IP address), to have free access to the Cochrane Library online, according to this Guardian article:

This is the best single source of reliable evidence about the effects of health care in the world. It is built up from statistical reviews of the available experimental evidence, combining the results from lots of different trials to make one big one, and offers the best chance of getting at the reality of what works and what doesn't. Being a trouble maker, the first thing I did was go to their site (linked from the Guardian Unlimited Bad Science pages) and look up acupuncture. Oh look, there are 22 studies already on smoking and acupuncture. Hang on: "There is no clear evidence that acupuncture, acupressure, laser therapy or electrostimulation are effective for smoking cessation."

Even without a UK IP you can browse the abstracts.
