Table 6 CISS (2017–2022) weighted counts and proportions (%) for (a) all exposed occupants (injured and uninjured) and (b) all injured occupants (occupants with cervical spine injuries) separated by their exposure to a rollover or non-rollover crash. Separate analyses are tabulated for cases where sex, seatbelt use, ejection status and fatality information was known. Abbreviations: R = rollover, NR = non-rollover, N = weighted counts, Nall = total weighted counts for each condition. The percentages for the rollover (R/N) and non-rollover (NR/N) conditions for each row sum to 100%, whereas the total column percentages (N/Nall) for each group sum to 100%
