Getting control of the control group

Lifestyles and emotions play important roles in many medical illnesses, and when scientists study potential treatments to help people stop smoking, get more exercise, overcome depression or improve their diet, they often compare patients who get a certain treatment to others who don’t. Researchers at Washington University School of Medicine in St. Louis, led by Ken Freedland, MD, say to accurately measure a new therapy’s the effectiveness, it is critical to carefully define comparison — or control — groups in those studies.  

Washington University opens clinic for treatment-resistant depression

Washington University School of Medicine has opened a clinic for patients with treatment-resistant depression that targets those who haven’t responded to standard therapies. When at least two therapies have been tried, and a patient still hasn’t responded, that patient is said to have treatment-resistant depression, according to clinic director Charles R. Conway, MD.
