This study was designed to break down the association of age, sex and seat belt use with risk of death for drivers of automobiles involved in a crash into two theoretical components: intrinsic severity of the crash and occupant resilience. ⋯ We conclude that in drivers involved in traffic crashes the association of age, sex and seat belt use with risk of death depends on the component of risk considered: severity of the crash or the occupant's resilience to energy.

Patient outcome after traumatic brain injury in high-, middle- and low-income countries: analysis of data on 8927 patients in 46 countries.
Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide. The burden of TBI is greatest in low- and middle-income countries (LAMIC), yet little is known about patient outcomes in these settings. ⋯ Reduced death rates following severe TBI in patients from high-income countries may be due to differences in medical care which may result in a higher proportion of patients surviving with a disability. Socio-cultural factors may explain the lower levels of disability after mild and moderate TBI in LAMIC.
