“For patients with a temperature recorded (n=494), a higher percentage of patients with CNS injury (AIS for head ≥3) was found for the RSI group than for the non-RSI group.” “The percentage of patients with ISS>15 was higher for the RSI group than for the non-RSI group (n=1292?).”

  1. 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.
