Published retrospective studies of the relationship between the use of oral contraceptives and disease have assumed that women are able to recall their oral contraceptive histories with reasonable accuracy. The validity of this assumption has been investigated by comparing oral contraceptive histories obtained from 75 women attending family planning clinics with the information contained in the clinic records. It is concluded that simple measures of oral contraceptive use, such as whether the preparations have ever or never been used, whether they are in current use, and the total duration of use, are likely to be remembered with adequate accuracy.
已发表的关于口服避孕药使用与疾病关系的回顾性研究假定，女性能够较为准确地回忆起她们的口服避孕药使用史。通过将75名前往计划生育诊所就诊的女性提供的口服避孕药使用史与诊所记录中的信息进行比较，对这一假设的有效性进行了调查。得出的结论是，口服避孕药使用的简单指标，如是否曾经使用过、是否正在使用以及使用的总时长，很可能会被准确地记住。
