Will individual participant data (IPD) for this trial be available (including data dictionaries)?
Yes
What data in particular will be shared?
The de-identified data set that will be collected for this analysis of the MIST+ trial will be available six months after publication of the primary outcome. The study protocol may be obtained from the Murdoch Children's Research Institute. Prior to releasing any data, the following are required: a data access agreement must be signed between relevant parties; the MIST+ trial investigators must see and approve the analysis plan describing how the data will be analysed; there must be an agreement around appropriate acknowledgment; and any additional costs involved must be covered.

Should the study investigators be unavailable, this role is delegated to the Murdoch Children's Research Institute. Data will only be shared with a recognised research institute, which has approved the proposed analysis plan.
