摘要：	The purpose of this report is to use the National Automotive Sampling System Crashworthiness Data System (NASS CDS) data for years 1997 through 2005 to determine whether there was a statistically significant relationship between the maximum severity of head, neck, and face injuries due to occupant roof contact that occurred in rollovers that were likely to be covered by Federal Motor Vehicle Safety Standard No. 216 and either post-crash headroom or vertical roof intrusion. The report uses the ordered probit and binary probit models, both unadjusted and adjusted for potentially confounding factors, to establish the existence of statistically significant relationships. The report presents estimates of 24 different models, 12 for intrusion and 12 for headroom. In all 24 models, the relationship between injury severity and the explanatory variable (intrusion or headroom) was statistically significant. / Availability Note: Product reproduced from digital image.
