Editor's Notes
A common problem when analysing clinical data is that of confounding. This occurs when the association between an exposure (say RSI) and an outcome (say body temp) is investigated but the exposure and the outcome are strongly associated with a third variable. An extreme example of this is Simpson’s paradox, in which this third factor REVERSES the effect first observed.
