Risks are involved in clinical research, as in routine medical care and activities of daily living. In thinking about the risks of research, it is helpful to focus on two things: the degree of harm that could result from taking part in the study, and the chance of any harm occurring.
After a research study is completed, the researchers carefully examine information collected during the study before making decisions about the meaning of the findings and about further research.
Randomization is a process used in scientific experiments to assign study participants to a treatment condition randomly. It may involve a simple method, like a coin toss or drawing numbers blindly from a basket, or it may involve more elaborate methods that involve a computer program.
The involvement of participants as partners in scientific research is crucial to its success. Breakthroughs in medical treatments have benefited millions of people, and this could not have happened without the involvement of people willing to participate in research.
Scientific research involves gathering data, information or facts in order to advance knowledge. At the Schroeder Institute, our research studies focus on tobacco use. All the studies listed on this site are clinical studies, meaning they involve human volunteers.
