There is a lot of debate about the merits of various health care systems (public and private) but a 10% difference in survival is nothing to sneeze at.

It will be interesting to see if Canada can raise the bar to the level set by the US under universal coverage.
Here is a link to a Canadian news outlets' report on the abstract.
