Adverse Event Reporting (AER)
Reports filed by patients and medical professionals to national and international regulatory bodies regarding adverse reactions to medical drugs and devices. See, for example, the US FDA’s system here. Bio-Markers
Biological markers refer to a broad subcategory of medical signs — that is, objective indications of the medical state of a patient, observed from outside the patient — and which can be accurately measured and the findings reproduced. For example, a blood test result. Medical signs stand in contrast to medical symptoms, which are limited to those indications of health or illness perceived by patients themselves. Blinding
When study participants do not know if they are receiving an intervention.
