Abstract
Simpson’s paradox was first recognized at the beginning of the 20 century, but few examples with real data have been presented. In this paper we present an example of this phenomenon from a multicenter study on nosocomial infections, and we try to explain intuitively this type of extreme confounding.Keywords
