  <body>
    <p>In the metadata for “Mobile Phone Ownership Is Not a Serious Barrier to Participation in Studies: Descriptive Study” (JMIR Mhealth Uhealth 2018;6(2):e21), the degrees for Sabrina L Smiley were listed in an incorrect order as “MCHES, MPH, PhD”. The degrees should have been ordered “PhD, MPH, MCHES”.</p>
    <p>The corrected article will appear in the online version of the paper on the JMIR website on April 25, 2018, together with the publication of this correction notice. Because this was made after submission to PubMed or Pubmed Central and other full-text repositories, the corrected article also has been re-submitted to those repositories.</p>
