Dose Response Curves

Abstract

When we graph the dose of a substance and the percentage of a population that responds to that dose, the result is called the dose-response curve. The x-axis is the dose, typically in a logarithmic scale. This means units on the x-axis increase by a power of 10, allowing us to compare a very wide range of doses on a single graph. The y-axis is the response, or the percentage of subjects that show a response.
