Videos were analysed and categorised into healthcare professionals (HCPs), non-healthcare professionals (non-HCPs) and other.

Overall, the videos were of poor quality with mean GQS and mDISCERN scores of 2.21 and 1.74 respectively. PEMAT understandability and actionability scores averaged 76.43% and 68.47% respectively. Videos uploaded by HCPs were generally of higher quality than others; this difference was statistically significant (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
