PrepTest 42, Section 2, Question 25
A study of 86 patients, all of whom suffered from disease T and received the same standard medical treatment, divided the patients into 2 equal groups. One group's members all attended weekly support group meetings, but no one from the other group attended support group meetings. After 10 years, 41 patients from each group had died. Clearly, support group meetings do not help patients with disease T live longer.
