Migraine and Acupuncture: A migraine is a particularly painful type of headache, which patients
sometimes wish to treat with acupuncture. To determine whether acupuncture relieves migraine
pain, researchers conducted a randomized controlled study where 154 patients diagnosed with
migraine headaches were randomly assigned to one of two groups: treatment or control. 68
patients in the treatment group received acupuncture that is specifically designed to treat
migraines. 86 patients in the control group received placebo acupuncture (needle insertion at non-
acupoint locations). 24 hours after patients received acupuncture, they were asked if they were pain
free. Results are summarized in the contingency table below. Test to see if migraine pain relief is
dependent on receiving acupuncture. Use a = 0.1.
