Note.

^±At both time points, according to the PTDS diagnostic criteria; PTDS= Posttraumatic Diagnostic Scale (Foa, et al., 1997); RR= Relative Rate [exp(β)]; 95% CI=95% Confidence Intervals;

^*=Models are adjusted for baseline PTDS, race and parental age;

^**=Models are adjusted for baseline PTDS, cardiac physiology and insurance type;

^Ϯ=Models are adjusted for baseline PTDS, race and RACHS-1 score.
