That implies the worst major centers have a maximum of 5% death rate. Steve Jobs would certainly go to one of the best hospitals, which I assume would have a much lower rate.
Nope. If there was any big variation between those worse and best "major centers", there would have been an examination and heads would have rolled (plus lawsuits). Big differences in death rates is not what differentiates a worse and a better clinic.
