In "Online Guide for Electronic Health Evaluation Approaches: Systematic Scoping Review and Concept Mapping Study ("J Med Internet Res 2020;22(8):e17774") the authors noted one error. The metadata erroneously listed the group author "EHealth Evaluation Research Group"as having contributed equally. This has been corrected, and the group author is no longer listed as having contributed equally. The correction will appear in the online version of the paper on the JMIR Publications website on August 21, 2020, together with the publication of this correction notice. Because this was made after submission to PubMed, PubMed Central, and other full-text repositories, the corrected article has also been resubmitted to those repositories.
