What Cochrane does not tell you is how many of those were funded by drug companies and whether the stated improvement was a worthwhile improvement.
A recent example was the recent scare over lung cancer from some anti hypertensive agents. Real increase but in reality I think they were talking about 10 extra cases per 100000 patient years.
So I am still with Helly on this, may be a real but probably not realistically better than placebo.
