Barely better than even odds in 4 out of 13 years.
*Please place "thanks for making my point" laugh here!*
Of course, once one allows for the placebo effect ( A PROPER scientific comparison that they absolutely refuse to do - I wonder why ) then you never even break better then even chances at all.

Flu deaths reality check
Credibility of flu models disputed
Do thousands of Canadians really die every year from the flu? The flu folks keep saying so. I've already heard it repeated several times this year and flu season has just started. This is what the Public Health Agency of Canada said in a recent press release: "Every year, between 2,000 and 8,000 Canadians die of the flu and its complications."
In a CBC interview a few weeks ago an editor of the Canadian Medical Association Journal said: "Four thousand to 8,000 people die every year of influenza."
It comes directly from the desk of Canada's chief public health officer. "The flu is serious," he tells us from his website. "Every year, between 2,000 and 8,000 Canadians die of the flu and its complications."
Did you ever wonder how they know that? The fact is, they don't know that. "This is a scientific guess. This is not the truth," Dr. Michael Gardam, director of the infection prevention and control unit at the University Health Network in Toronto and a longtime flu watcher, told me.
The fact is, no one knows how many people die after being infected with the flu virus. The death estimates are not based on body counts, lab tests or autopsies.
The "2,000 to 8,000" numbers are based on computer models — a statistical guess that comes out of the end of a mathematical formula that makes a range of assumptions about death and flu.
Another model assumes that every extra death that happens in the winter is a flu death. At the risk of oversimplifying, this is the basic formula of that model: winter deaths (minus) summer deaths = death by flu virus.

Hmmmm...computer models eh?
Just like the predictions of man maid global warming that could NEVER possibly happen.
BE AFRAID!!! BE VERY VERY AFRAID!!!!
