Edited sentence: A 2011 review of review articles concluded that, except for neck pain, acupuncture was of doubtful efficacy and accompanied by serious risks and adverse effects, including 38 cases of infection, 42 cases of trauma and 5 cases of death.Acupuncture being effective beyond the placebo effect has never been proven, except some pain relieving applications, though the latter results are somewhat inconsistent as well.Although evidence exists for a very small and short-lived effect on some types of pain, several review articles discussing the effectiveness of acupuncture have concluded it is possible to explain this as a placebo effect.Evidence for the treatment of other conditions is equivocal.Publication bias is a significant concern when evaluating the literature.Systematic reviews have concluded that acupuncture is no more effective than nonpenetrating stimulation of one point to reduce some types of nausea.The authors considered the adverse events to be statistically significant.The evidence for acupuncture's effectiveness for anything but the relief of some types of pain and nausea has not been established
