Survival function curves for traumatic brain injury (TBI) versus Control groups. Participants with TBI and Controls not developing novel psychiatric disorder (NPD) by their long-term follow-up, or by their one-time assessment, respectively, were censored at that time-point. Inspection of the survival function curves reveals the TBI group initially had a steeper change in events (onset of NPD-any) compared with the control group, but over the 10 to 15 years post-injury, the slopes are similar for both groups. Overall, the TBI group has a shorter survival with regard to onset of NPD-any. Color image is available online.
