We read the paper by Stengel et al. in the November 2009 issue with great interest.

Some issues, however, cannot remain unchallenged. They wrote that a “simple explanation”
for the fact that the pan-CT group

was associated with a significantly greater probability of survival is that whole-body
CT detects more injuries. This could result in a higher ISS/NISS and therefore greater
estimates of the risk of death. Indeed, the so-called “Will Rogers phenomenon” (removing
one observation from one group to another, thereby raising the mean value of both
groups) cannot be excluded completely, but we think that its influence is at best
marginal.To read this article in full you will need to make a payment
