AJTM require a Data Availability Statement for any submitted research articles. AJTM has three policies on data sharing:
Tier 1:
We require that the data generated by your research that supports your article be made openly and publicly available upon publication of your article. Where it is not possible or viable to make data openly available (due to confidentiality or sensitivity issues), they should be shared through a controlled access repository.
Tier 2:
We strongly encourage that data generated by your research that supports your article be made available as soon as possible, wherever legally and ethically possible
We require data from clinical trials to be made available upon reasonable request
We require that a data sharing plan must be included with trial registration for clinical trials. Changes to the plan must be noted in the Data Availability Statement and updated in the registry record (to comply with ICMJE recommendations)
Tier 3:
We strongly encourage that data generated by your research that supports your article be made available as soon as possible, wherever legally and ethically possible.
