The term "registered report" was first coined by theCenter for Open Science, and refers to the publication of a research article that is published in two stages:

1. Publication of a peer-reviewed researchprotocol (a stage 1 Registered Report, orRR1). At JMIR Publications, protocols (RR1s) are published inJMIR Research Protocols, whichguarantees the subsequent acceptance of papers containing results of the protocol (see below) in one of the JMIR Publications journal, independently of whether the results research turns out to be negative. The JMIR journal is selected by the Editor and depends on the study's focus and scope. 

2. Publication of a peer-reviewed research paper containing the protocol'sresults (a stage 2 Registered Report, orRR2).

Registered Reports are important because they enhance transparency and reduce publication bias. For further information on Registered Reports seeRegistered Report (Center for Open Science).

At JMIR Publications, Registered Reports (both RR1 and RR2 papers) are given a persistent identifier called anIRRID (International Registered Report Identifier), the purpose of which is to further enhance transparency by providing a machine- and human-readable mechanism for associating RR2s to RR1s. For more information, seeWhat is an International Registered Report Identifier? 

RR1's (or protocols) have sometimes the PRE or DE qualifier :

 PRE-registered: The protocol was published before any data were collected or available

DE = Data existing: The protocol was published when the data were already collected (if enrolment of participants has started, then this is considered DE)

If the results paper (RR2) is known, then these logos link to them.
