关于口服避孕药和子宫肌瘤之间关系的资料中有较多分歧。在一份英国皇家普通医学院的报告中,目前正服用避孕药者与从未服药者比较,其相对危险性(RR)仅0.4,而以前服药者的危险性类似于从未服药者。但Walnut Creek避孕药研究中心在一组 505例子宫肌瘤的研究中,曾服避孕药者与从未服药者比较其RR是1.5倍,且危险性随着服用持续时间的延长而增加。上述矛盾的结果可能由于病例的选择和诊断的差异所造 There is more disagreement about the relationship between oral contraceptives and uterine fibroids. In a report from the British Royal College of General Physicians, the relative risk (RR) of those who are currently taking contraceptives compared to those who have never taken them is only 0.4, and the risk of former drug users is similar to those who never used drugs. However, in a group of 505 cases of uterine fibroids, the Walnut Creek Contraceptive Research Center had 1.5 times the RR for those who had taken contraceptives compared with those who had never taken it, and the risk increased with the duration of taking it. The above contradictory results may be due to differences in case selection and diagnosis.
