Krugman lies again

The lying Bush-hater Paul Krugman writes:
"My chance of surviving prostate cancer — and thank God I was cured of it — in the United States? Eighty-two percent," says Rudy Giuliani in a new radio ad attacking Democratic plans for universal health care. "My chances of surviving prostate cancer in England? Only 44 percent, under socialized medicine."

It would be a stunning comparison if it were true. But it isn’t. ...

Mr. Giuliani got his numbers from a recent article in City Journal, a publication of the conservative Manhattan Institute. The author gave no source for his numbers on five-year survival rates — the probability that someone diagnosed with prostate cancer would still be alive five years after the diagnosis. And they're just wrong.

You see, the actual survival rate in Britain is 74.4 percent. That still looks a bit lower than the U.S. rate, but the difference turns out to be mainly a statistical illusion. The details are technical, ...
So Krugman calls Guiliani a liar because he got a statistic from an article that does not cite its source. But Krugman does not cite a source for his 74.4% figure either.

On Krugman's blog, he cites this:
Five-year survival rates were 95 percent in the U.S. and 60 percent in the United Kingdom, which includes Britain, in 1993-1995, the most recent time period with data to compare, the group said.

Today, rates are higher -- 99 percent in the U.S. and an estimated 74 percent in the U.K.
Assuming that this is Krugman's source, he is falsely presenting the 74% figure for the UK as being comparable to Guiliani's 82% figure for the USA. It is not. Even by Krugman's own measures, USA prostate cancer survival rates are much higher than the UK's.
