    <p>In the paper “The Association Between Pain Relief Using Video Games and an Increase in Vagal Tone in Children With Cancer: Analytic Observational Study With a Quasi-Experimental Pre/Posttest Methodology” (J Med Internet Res 2020;22(3):e16013) the authors noticed that one of the authors was not listed on the original published manuscript. The missing author was Mario Alonso Puig; they are first author on the corrected manuscript.</p>
    <p>Mario Alonso Puig’s affiliation will be listed as “Juegaterapia Foundation, Madrid, Spain” and will appear as affiliation 1 in the corrected manuscript. Author affiliations 1-4 in the original published manuscript will be renumbered to affiliations 2-5 in the corrected manuscript.</p>
    <p>The correction will appear in the online version of the paper on the JMIR website on July 7, 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.</p>
