Trauma registry is a legitimate source for research but carries several limitations that should be considered. Both SI and CVRI were similar moderate predictors of early death in the entire trauma population though inferior to GCS, RTS and WRTS hence cannot be considered competing predictors of death. CVRI was found a fair predictor of early death preferable to SI in the subpopulations undetected as carrying risk by either GCS and RTS each of which missed nearly half of the entire early trauma deaths.
