Oxidation-Reduction Potential as a Biomarker for Severity and Acute Outcome in Traumatic Brain Injury

Figure 1

Assessment of survival based on hospital discharge can best be predicted by icORP on day 4. (a) Admission measures of icORP were not significantly different between patients with ultimately different discharge statuses. (b) By day 4 after injury, there was a significant difference between groups, with those that were ultimately discharged to a hospice or who died having much higher icORP values than any other discharge status. Those discharged to acute care facilities were the lowest but this failed to reach significance ( and 0.08 between home and intermediate, resp.). (c) icORP values on day 7 were, again, not significantly different between the groups. (d) The ROC curve showing the AUC for day 4 icORP values. See Table 3 for ROC results. Data are presented as means ± standard error of the mean (sem); means significantly greater than all other groups.
