You have developed a new treatment for the long-term effects of cancer and wish to test it. You find a group of patients who were diagnosed with cancer, and declared “cured’ over 6 months ago but report lingering symptoms. You give your treatment to 15 of them and a placebo to 15 other patients. Your treatment is inexpensive and has few side effects. You have each person assessed by a medical professional after 3 months of treatment. Scores on this test are based on the number of symptoms each patient reports from a list of 25 known symptoms commonly reported by people after recovering from cancer.
