The percentage of survivors decreasing, increasing, or having no change in GOS-E scores over each time interval is shown. Only 13% of survivors had a decline in their functional status from 3 to 24 months, whereas 69% of severe TBI survivors demonstrated an increase in their functional status within this time interval. More important, this table demonstrates from 6 to 24 months there is an increase in GOS-E scores of 50% during a time interval thought to be when survivors plateau in their progression. Patients who died between 3 and 24 months have been excluded from this table.
