Corrigenda and Addenda
In the originally published paper, the footnotes under Table 3 were incorrect.
The footnotes originally appeared as follows:
bO: not included in the questionnaire
cX: included in the questionnaire
These have now been corrected to the following:
bO: included in the questionnaire
cX: not included in the questionnaire
The correction will appear in the online version of the paper on the JMIR Publications website on March 03, 2021, 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.
