[2] Editor-in-chief Gunther Eysenbach commented that the spin-off journals would eventually have their own boards and that the fast-track option does not affect the quality or integrity of its peer-review processes.

These include:[6] In June 2023, JMIR Publications announced that 14 of their 34 journals had received Impact Factors, many ranked in the top quartile (Q1) of their respective disciplines.

JMIR Publications also publishes the JMIRx series of "superjournals", described as a form of Overlay journal, which conduct peer-review on top of entire preprint servers and offers publication of the version-of-record.

[8] JMIR Publications created superjournals for Preprint servers like MedRxiv (JMIRx Med[9]) and BioRxiv (JMIRx-Bio[10]).

[13] In 2022, JMIR Publications announced that JMIRx Med was accepted as the first overlay journal to be indexed in PubMed.
