The histories of oral contraceptive (OC) use provided by women participating in a study of hepatocellular adenoma (HCA) were compared with records obtained from their physicians. In the HCA study two memory aids were used to assist women in their recall: a calendar of significant events during a woman's lifetime to which she might relate her use of OCs and a book of colour photographs of the 90 OC preparations available up to the time of the study. Using the number of months of a woman's history which could be checked against physician records (mean for all women of 33 months) as the denominator, the highest proportion of concordance was for month-specific duration of OC use (90%) with lower agreement for duration and brand (62%) and duration, brand, and dose (54%). Agreement was better for cases than for controls.
在一项肝细胞腺瘤（HCA）研究中，将参与研究的女性提供的口服避孕药（OC）使用史与其医生记录进行了比较。在HCA研究中，使用了两种记忆辅助工具来帮助女性回忆：一本记录女性一生中重大事件的日历，她可以将自己使用OC的情况与之关联；以及一本收录了研究时可用的90种OC制剂彩色照片的书。以可与医生记录核对的女性用药史月数（所有女性的平均值为33个月）作为分母，一致性比例最高的是特定月份的OC使用时长（90%），而在使用时长与品牌（62%）以及使用时长、品牌和剂量（54%）方面的一致性较低。病例组的一致性优于对照组。
