Tranexamic Acids: Can We Pick Patients That Might Do Better?

There's nothing else in the, including in GCS or in the AIS subgroups alone that enabled us to select group patients that would do better on the primary outcome measure. We have done some further analysis of the head injured patients and broken down the AIS and GCS characteristics of the patients into four groups. And I think probably look at look hard at whether you want to give it between two and three hours now for mortality benefit even. But without data you can cut it up a whole lot of different ways and try and find some things out.
