Summary Introduction
To review:
The method to avoid the placebo effect in a new drug test.
Introduction:
A placebo is a false treatment that looks like the real treatment, but is not. A placebo does not contain the active substrate that is supposed to help the treatment, it can be a sugar pill that looks exactly like a real capsule or an injection containing just water. During the clinical study, researchers give placebos to a specific group known as a placebo group to compare the effectiveness of the new drug that is given to another group known as the treatment group. It allows researchers to understand what would happen if the drug is not given.

- The Esp gene encodes a protein that alters the structure of the insulin receptor on osteoblasts and interferes with the binding of insulin to the receptor. A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2). Which of the following claims is most consistent with the data shown in Figure 2 ? A Esp expression is necessary to prevent the overproduction of insulin.
