The objective was to explore the variability in in vitro fertilization (IVF) success rates.
Published success rates from IVF clinics in North America were investigated to establish types of biases and potential inaccuracies.
Success rates reported by IVF clinics vary with regard to the indices and patient populations used to compute them. Selection bias and misunderstood statistics are major factors contributing to the inappropriateness of certain rates.
The influence of privatization and market forces also may contribute to the need to oversimplify IVF statistics.
旨在探讨体外受精(IVF)成功率的变异性。
对北美体外受精诊所公布的成功率进行调查,以确定偏差类型和潜在的不准确之处。
体外受精诊所报告的成功率在用于计算的指标和患者群体方面存在差异。选择偏差和对统计数据的误解是导致某些成功率不恰当的主要因素。
私有化和市场力量的影响也可能导致有必要过度简化体外受精统计数据。
