- Masking Details
- Masking will be done by an independent clinical trials supply company. It will involve the removal of the original manufacturer's label and replacement with the clinical trial label bearing the randomisation number, which will be used as the pack identification. Apart from the randomisation number, all pack label texts will be identical for tranexamic acid and placebo.

- Access Criteria
- Totally anonymised data (without random allocation, patient, country and site identifiers) will be freely available.Where random allocation codes, country/site identifiers are requested, appropriate pre-specified analysis plan will need to be submitted to the Trial Management Group for review and if necessary, appropriate Ethics Committee approval will be required.
Data will be shared publicly when all planned analyses are completed by the CRASH-4 Trial Collaborators. This will be hosted on freebird.lshtm.ac.uk
