The staff who were treating you/the participant for your head injury should have given you a participant information sheet about the CRASH-4 trial. You can also download the brief information sheet and additional information from here.
If you have any questions or concerns about your treatment, please contact your doctor in the first instance.
Please note that these documents are generic versions for information only.
There are hospital and ambulance service specific variations and participants and relatives/representatives should always read the information sheet and consent form given to them by the doctor, paramedic or nurse treating the participant.
