Seems there may be something lacking in the information supplied to the BBC by the student researcher and his internet friends.
Seems he wants individual patient information from studies, he admits is not standard practice, and because it's not supplied says the study is
biased.
Then to top it all he fails to even list the studies he investigated. That was handy as it protects his theory from the investigation bias he claims
is rampant in studies not supplying the raw data.
