Oyetunji et al1 performed a meticulous statistical analysis of a large nationwide database concerning admission BP and subsequent mortality as a consequence of traumatic injury. The statistical methods used are time-consuming and available for use only in very large data sets. Nevertheless, Oyetunji et al1 showed, with good statistical power, that a “normal” SBP may not predict a good outcome in elderly patients. For this study, elderly was defined as 65 years and older.
