  <body>
    <p>In “Characterization of Anorexia Nervosa on Social Media: Textual, Visual, Relational, Behavioral, and Demographical Analysis” (J Med Internet Res 2021; 23(7):e25925), the authors noted one error.</p>
    <p>In the originally published paper, a reference was mistakenly placed in the following sentence in the Introduction – Background section:</p>
    <disp-quote>
      <p>EDs, such as AN, are strongly related to risk factors including perfectionistic traits, parenting style [2], and the existence of comorbid mood disorders such as depression, of which 33%-50% of anorexia patients experience.</p>
    </disp-quote>
    <p>To address this issue and to avoid a misinterpretation of the conclusions of Reference 2, which analyses but does not state that there is a strong relation between AN and parenting style, the sentence has been corrected as follows:</p>
    <disp-quote>
      <p>EDs, such as AN, are related to risk factors including perfectionistic traits [2], and the existence of comorbid mood disorders such as depression, of which 33%-50% of anorexia patients experience.</p>
    </disp-quote>
    <p>The correction will appear in the online version of the paper on the JMIR Publications website on October 12, 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.</p>
