Example scenario: a male smoker asks his doctor to help him give up smoking. The man says he has tried nicotine patches and gum, but these did not work. He has read an article about hypnosis helping, and asks what the doctor thinks.

Patient	Intervention	Outcome
male smoker	hypnosis	smoking cessation

In men, does the use of hypnosis help smoking cessation?

This is a Therapy question, so finding a systematic review of trials, or a single randomised controlled trial in the Cochrane Library would be ideal.
