Registered Report
Registered reports adhere to the highest ethical standards in research and require a protocol to be published (e.g. in JMIR Research Protocols), ideally before data collection. Publishing a protocol (Registered Report Stage 1, or RR1) prevents bias and JMIR's "acceptance in principle" policy for projects with published protocol facilitates publication of study results even if they are negative.
This category/journal section/e-collection is for papers reporting the results (Registered Report Stage 2, or RR2). The IRRID in the abstract links back to the DOI of the protocol.
