| dose-ranging | A preliminary clinical trial in which the amount of the drug is either periodically increased or increased with each new trial arm that is added. Used to determine how a drug is tolerated in people. (09 Oct 1997) |
|---|---|
| dose-response curve | This is a graph to show the relation between the dose of a drug or other chemical and the degree of response it produces, as measured by the percentage of the exposed population showing a defined, often quantal, effect. (09 Oct 1997) |
| dose-response relationship | Relationship in which a change in the amount, intensity, or duration of exposure is associated with a change in risk of a specified outcome. (05 Mar 2000) |
| dose-response relationship, drug | The relationship between the dose of an administered drug and the response of the organism to the drug. (12 Dec 1998) |
| dose-response relationship, immunologic | A specific immune response elicited by a specific dose of an immunologically active substance or cell in an organism, tissue, or cell. (12 Dec 1998) |
