Avis NE, et al. - Data from three randomized controlled trials of interventions for hot flashes (two acupuncture trials, one yoga trial) were pooled and analyzed to compare the effectiveness of interventions. Perimenopausal or postmenopausal women experiencing ≥4 hot flashes/d on average were recruited in all the three studies. Reduction achieved in hot flash frequency was statistically similar between acupuncture, yoga, and health and wellness education classes when compared with controls.
