Data Do Not Support Effectiveness of Acupuncture for Improving Live Birth Rate in Women with Polycystic Ovary Syndrome

Recently, the arguments raised by Gang and Jing have been published in Chinese Journal of Integrative Medicine, concerning the randomized controlled trial （RCT） of our team published in JAMA. The conclusions of Gang and Jingo） result not only from misunderstanding of the aims of our study,） but also a lack of basic knowledge for the design of RCT and the limitations on the content, and hence the length, of the primary outcome article in high-impact journals （i.e. 2,500 words and a total of 5 figures/tables in JAMA）. We will address their main critiques point by point below.

剖宫产后阴道分娩的影响因素研究

目的探讨剖宫产后阴道分娩情况及其影响因素,为提高分娩成功率提供参考依据。方法选取2014年7月~2017年2月剖宫产后阴道试产的249例孕妇,采用单因素分析结合多因素Logistic逐步回归分析探讨剖宫产后阴道分娩的影响因素。结果多因素Logistic逐步回归分析显示,相对于子宫下段肌层厚度<2 mm的产妇,子宫下段肌层厚度≥2 mm的产妇阴道分娩失败少(OR=0.17,95%CI:0.03~0.96,P=0.045);相对于无导乐陪伴的产妇,有导乐陪伴的产妇阴道分娩失败低(OR=0.18,95%CI:0.03~0.94,P=0.042);相对于缩宫素临产的产妇,自然临产产妇阴道分娩失败低(OR=0.16,95%CI:0.03~0.97,P=0.046);相对于距前次剖宫产时间<2年的产妇,距前次剖宫产时间≥2年的产妇阴道分娩失败低(OR=0.04,95%CI:0.01~0.34,P=0.003);相对于无阴道分娩史的产妇,有阴道分娩史产妇阴道分娩失败低(OR=0.10,95%CI:0.02~0.59,P=0.011)。结论子宫下段肌层厚度≥2mm、有导乐陪伴、自然临产方式、距前次剖宫产时间≥2年和有阴道分娩史是剖宫产后阴道分娩成功的保护因素。
