This paper introduces a method for correcting spontaneous abortion rates by taking into consideration the fact that a number of spontaneous abortions are "prevented" by induced abortions. This correction may be important in settings of high induced abortion incidence. The method is then applied to the data of the Italian region of Lombardy. The results obtained are compared to those obtained with previous correction methods, and it is concluded that the present method is useful and appropriate when data on induced and spontaneous abortions are available by gestational age.
本文介绍了一种校正自然流产率的方法，该方法考虑到一些自然流产是由人工流产“预防”的这一事实。在人工流产发生率较高的情况下，这种校正可能很重要。然后将该方法应用于意大利伦巴第地区的数据。将所得结果与采用先前校正方法所得结果进行比较，得出的结论是，当可获得按孕周划分的人工流产和自然流产数据时，本方法是有用且合适的。
