Significant at the 0.05 level, two-sided test, corrected for false discovery rate.
No collision (n = 81), “other” (n = 8), and “don’t know (n = 8).
None (n = 12) and “don’t know” (n = 31).
Moderate or severe injuries. Unstandardized values used for mean/SE reporting. Models use standardized values with mean=0 and standard deviation=1.
Max score of the nine AIS regions.
Self-reported 0–10 scale on pain intensity right now. Unstandardized values used for mean/SE reporting. Models use standardized values with mean=0 and standard deviation=1.
Sum of all differences in each somatic symptom between 30-day (self-reported 0–10 scale) and right now (self-reported 0–10 scale). Unstandardized values used for mean/SE reporting. Models use standardized values with mean=0 and standard deviation=1.
