secondary endpoint

A secondary endpoint in a clinical trial refers to an additional outcome or measure used to assess the effects of a treatment, besides the main goal. While the primary endpoint focuses on the main question, secondary endpoints provide broader insights into other possible benefits or safety aspects of the treatment. For example, in a new medication trial for diabetes, the primary endpoint might be blood sugar levels, while secondary endpoints could include blood pressure or cholesterol levels. These help researchers understand the full impact of the treatment, supporting a comprehensive evaluation of its effectiveness and safety.
