Question
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 151 patients diagnosed with migraine
headaches were randomly assigned to one of two
groups: treatment or control. 70 patients in the
treatment group received acupuncture that is
specifically designed to treat migraines. 81 patients in
the control group received placebo acupuncture
(needle insertion at non-acupoint locations). 24 hours
after patients received acupuncture, they were asked
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 =
0.01.
