"A study published early February in the British Medical Journal examined the link between acupuncture and successful in vitro fertilization…..The authors pooled the seven studies in a meta-analysis to find that the odds ratio — the odds of pregnancy through IVF and acupuncture divided by the odds of pregnancy through IVF without acupuncture — was 1.65. Here the word 'odds' is used in the statistical sense, not the layman meaning…..The media reported this figure as if acupuncture increases the success rate of IVF *by 65 percent*, misunderstanding what is meant by the odds ratio. The actual increase in pregnancy likelihood according to this meta-analysis is about ten percent. This alone makes the results far less impressive than they sound."
