Glossary of Terms
We know that many of the concepts used on this site can be difficult to understand. For that reason, we have provided you with a glossary to help you make sense of the terms used in Comparative Effectiveness Research. Every word that is defined in this glossary should appear highlighted throughout the Web site. When you come upon a highlighted term and would like to read the full definition, you can either click on the word to visit the glossary or roll your mouse over the word for a pop-up definition.
Definition: A scientific idea that can be tested in a research study. The hypothesis is the scientific idea that led to the research study.
Example: For example, the National Institutes of Health (NIH) sponsored a large study that tested the hypothesis that the combination of glucosamine and chondroitin brings better pain relief for people with arthritis of the knee than other common treatments for arthritis.
