  1. Note: total participants n = 988; total participants with persistent damage n = 119; total participants without persistent damage n = 846; missing n = 23
  2. *Adjusted odds ratios are adjusted for age, sex, pre;existing illness, deprivation, local authority, ethnicity, marital, education and employment statuses
  3. **the p;values are for the test of the null hypothesis that the aORs for those with and without persistent damage are equal
  4. ***for PTSD, because there were no cases in the unaffected group, the group without persistent damage was taken as the reference group when comparing this group with that with persistent damage
