Dose-Response

Dose-Response: The dose-response curve is a graphical representation of the relationship between the dose of a drug or other treatment and the response of the organism. The response may be measured by any suitable means, such as survival, change in body weight, change in tumor size, or change in enzyme activity. The curve may be linear or nonlinear; if it is nonlinear, it may be S-shaped (sigmoid) or U-shaped.
