In 1974, screening trials indicated that both the sensitivity and specificity of single-view mammography are high. During the subsequent three years, 11 cases of breast carcinoma have been detected in the study population of 6,845 women aged 40 or older. The average incidence was three cases per year, compared to the expected rate of 8.9. The age-adjusted incidence rate in 1975, the year after screening, was 55.4 per 100,000, which is 40% of the expected rate of 140. In 1976 it was 75.9, or 54% of the expected rate of 141. These results support the view that single-view mammography is an efficient screening method, at least in the subject population described.
1974年，筛查试验表明单视图乳房X线摄影的敏感性和特异性都很高。在随后的三年里，在6845名40岁及以上女性的研究人群中检测出11例乳腺癌。平均发病率为每年3例，而预期发病率为8.9例。筛查后一年即1975年的年龄调整发病率为每10万人55.4例，为预期发病率140例的40%。1976年为75.9例，即预期发病率141例的54%。这些结果支持了这样一种观点，即单视图乳房X线摄影是一种有效的筛查方法，至少在所描述的受试人群中是如此。
