Study of the prevalence rates of uterine cervical carcinoma in situ among women attending centres of Planned Parenthood of New York City, Inc., showed a small but statistically significant difference between the population choosing and using the diaphragm and the population choosing and using oral steroids for contraception. This can be attributed either to a decreased prevalence rate for women using the diaphragm or to an increased rate for women using oral steroids. The reason for the difference is not apparent from these data.
对纽约市计划生育协会各中心女性原位子宫颈癌患病率的研究表明,在选择并使用子宫帽和选择并使用口服类固醇进行避孕的人群之间,存在微小但具有统计学意义的差异。这可能是由于使用子宫帽的女性患病率降低,或者使用口服类固醇的女性患病率升高。从这些数据中,差异的原因并不明显。
