How can I get an International Registered Report Identifier?
Since May 2018, authors/projects automatically receive an International Registered Report Identifier (IRRID) if they submit and publish a research protocol (=RR1 stage 1 papers) in the journal JMIR Research Protocols or other participating journals.
What is an International Registered Report Identifier?
An International Registered Report Identifier (IRRID) identifies a research project by its' protocol (RR1 stage 1 papers) and links it to all subsequent results papers (RR2 papers) by using the same stable unique identifier, which is essentially the DOI of the protocol paper (What is a Registered Report?).
An RR1 IRRID - issued by JMIR Research Protocols - also signifies that the project is in principle accepted for publication in any other JMIR journal, and the identifier should be cited in the abstract of the subsequent results (RR2) paper.
(Note that IRRIDs were previously referred to as RRID's but to avoid confusion with the Research Resource Identifiers initiative (http://www.rrids.org) they are now referred to as IRRID's)
IRRIDs can and should be used in addition to the existing clinical trials registration system (Does my trial (RCT) have to be registered?).
The following screenshot shows an example of a research protocol with an assigned IRRID:
The IRRID consists of the following elements:
- A prefix "RR1-" (PRR1, DERR1) or "RR2-", indicating if this is a stage 1 (protocol) or stage 2 (results) paper, respectively
- The prefix PRR1 is used instead of RR1 if the protocol was submitted before data collection and analysis, i.e. the protocol was actually PREregisted (Example: PRR1-10.2196/10491).
- The prefix DERR1 is used when submission of the protocol took place after data collection (DE=Data Exist) but before data analysis
- RR1 indicates that either the timeline is undetermined or the protocol was submitted after data collection and analysis (POST)
- RR2 indicates a results paper, linking back to the respective RR1 protocol/registered report (ideally, PRR2 or DERR2 are used as well)
- The prefix RR1- (PRR1-, DERR1-) as well as RR2 (PRR2-, DERR2-) is followed by the DOI of the protocol (RR1) paper, and DOI in itself consists of two parts:
- prefix indicating the publisher of the protocol (RR1) (10.2196 is the DOI prefix for JMIR Publications, but if the registered report is published elsewhere it would be a different number)
- This is followed by the internal publisher manuscript tracking number of the protocol (RR1) paper or ideally the latter part of the DOI (recognizing that not all RR1-publishers actually know the DOI before publication, a manuscript tracking number or something similar can be used in lieu)
Authors of any subsequent results paper based on a stage 1 paper (protocol) should - in addition to citing the protocol in their bibliography - add the IRRID to their abstract, replacing RR1 with RR2. The identifier after RR1/RR2 remains stable.
For example, any subsequent results papers for the protocol RR1-10.2196/7425 would carry the IRRID: RR2-10.2196/7425. Remember that it is the DOI of the protocol that is used in all subsequent RR2's.
In the future, at JMIR publications there will be a field in our submission form for the IRRID as well (for the time being, just add it to the abstract for RR2 submissions).
IRRIDs greatly facilitate the crosslinking of registered reports across journals. Please also add the Registered Report Identifier to the abstract of the results paper, even if it is not submitted to a JMIR journal but to a different journal.
We invite other publishers and journals to adopt the IRRID system to link back to protocols/registered reports when they publish results (RR2) papers by identifying IRRIDs in the abstract.
