Table 1.

Data for all risk curve calculations of NASS delta-V data corrected for bias and scatter error. The ID Code describes the subsample of the 1997 – 2006 NASS dataset. The first character indicates belt status (B = belted, U = unbelted, A = all), the second character indicates age group (Y = < 30 yrs, M = 30 – 60 yrs, O = > 60 yrs, A = all), and the third character indicates gender (M = male, F = female, A = all). Both raw (R) and weighted (W) sample sizes are given. α and β coefficients are for a Weibull distribution (eq. 11 for the exposure distribution and eq. 6 for the risk function) where x is delta-V in units of kilometers per hour.
