Table 2. Important Considerations while Performing Risk Adjusted Analyses using NTDB Data to Study Trauma Outcomes.

In addition to the relevant specific factors that may need to be adjusted for, the following five “basic minimum” co-variates, which are known to predict trauma outcomes should be controlled for:
