The most common source of upload was doctors/medical institutions (33%), and majority of the content was about general information (27%). The mean modi ed DISCERN, GQS and JAMA scores were 3.24, 3.25 and 2.17, respectively. These scores were correlated with each other and signi cantly higher in videos uploaded by doctors/medical institutions. Of the videos, 25.5% were poor, 30.5% were moderate, and 44% were high-quality. High-quality videos were signi cantly shorter than poor qualities. Poor-quality videos had the highest view ratio.
