Review of evaluative studies on electronic fetal monitoring (E.F.M.) during labour shows that the conclusions of the five published randomized controlled trials have not been applied. There is a discrepancy between the widespread use of the method and the lack of proof of its efficacy in the controlled trials. This discrepancy can be related to methodological problems (insufficient number of cases, judgment criteria, compared types of care). It also shows that the conclusion concerning the possible net benefit or net harm of E.F.M. depends on the absence of such benefit, on the unit chosen to combine advantages and disadvantages. Based upon the same set of estimates for advantages and disadvantages the conclusion is in favor of E.F.M. when the chosen unit is utility whereas the conclusion is different in a cost-benefit analysis.
对分娩期间电子胎儿监护（E.F.M.）评估研究的综述表明，五项已发表的随机对照试验的结论尚未得到应用。该方法的广泛使用与对照试验中缺乏其有效性的证据之间存在差异。这种差异可能与方法学问题（病例数量不足、判断标准、对照护理类型）有关。这也表明，关于E.F.M.可能的净益处或净危害的结论取决于是否缺乏此类益处，取决于用于综合利弊的单位。基于同一组利弊估计，当所选单位是效用时，结论有利于E.F.M.，而在成本效益分析中结论则不同。
