Will individual participant data (IPD) for this trial be available (including data dictionaries)?
Yes
What data in particular will be shared?
Qualified researchers may contact the FIL board at [email protected] to share invidual-level patients' clinical data analysed for this manuscript (for the avoidance of doubt, no identifiable data, such as name, address, hospital name, date of birth, or any other identifying data, will be shared and should not be requested).

When will data be available (start and end dates)?
In compliance with the domestic ethics guideline and applicable legislation, invidual deindentified patients' data underlying the results reported in the publication article (including study protocol, statistical analysis plan and data coding) can be shared until 5 years after the publication of the article.
Available to whom?
For each data sharing request, it is essential that a proforma (available on request) is completed that describes the general purpose, specific aims, data items requested, analysis plan and acknowledgment of the trial management team. Requests will be reviewed based on scientific merit and ethical principles. Requestors who are granted access to the data will be required to complete a data sharing agreement that will be signed by the requester and FIL.
