Anatomy of a case report
Writing case reports: A balanced perspective As educators, we often encounter students eager to write case reports. Dr. Coidado fielded so many queries and requests for assistance that she reached out to me to help her create this resource. While I have many reservations about this effort and my own personal biases, it’s important that […]
