2.1. Student Doctor Network pathology forum

On February 17, 2018, the SDN pathology forum threads [16] were sorted by views. The 50 all-time most-viewed pathology thread titles were saved as a portable document format (PDF) file. This process was repeated for 14 major medical specialties: anesthesiology, dermatology, emergency medicine, family medicine, internal medicine, neurology, obstetrics and gynecology, orthopedic surgery, otolaryngology, pediatrics, physical medicine and rehabilitation, psychiatry, radiology, and surgery. For the pathology threads, additional information was saved: the date of the first and last comment for each thread and the number of views for each thread. The dataset is accessible through Mendeley Data (DOI: 10.17632/fzyhh7nhc8.4).
