The Clinical Evaluation Report (CER) is a document containing clinical data about a medical device. This data must be collected, appraised, and analysed in a structured way. After completion, a CER is reviewed by the Notified Body (NB), before the device is granted initial or renewal market approval (the CE-mark). Adapted from: Pritchard G. Clinical evaluation reports from the medical writer’s perspective! Med Writ. 2017;26(2):14–9.
