If you have a substantial comment, feedback, a critique or additional information related to a paper recently published in a JMIR journal, we encourage you to submit a short letter to the editor.
This is done using the regular submission system. As "section" choose "Letter to the Editor" from the drop-down list in the submission process.
The letter should be no more than 500 words, and should have 1-5 references, where the first one should cite the JMIR paper you are commenting on.
Note that we will invite the original JMIR authors to review and possibly comment on / reply to your letter. We may publish their reply.
Letters must comment on a previously published JMIR paper (usually not older than 6 months) and must contain important additional information or critical questions adding value to the understanding of the published paper. We do not allow brief research reports as letter, please submit a brief original paper instead (APFs apply).
Letters are free of charge for the author.
If you are an author of a previously published JMIR paper, do not submit a letter, but a correction or addendum.
