  1. SE Standard error, TBI Traumatic brain injury, SCI Spinal cord injury, MVC Motor vehicle crash
  2. aMortality rates for total and subgroup traumatic brain injury (except for the 7 age groups) were age-standardized based on the population of China in 2010
  3. bMortality trends from 2006 to 2013 were examined using the Cochran–Armitage trend test
