Five experienced screeners independently and blindly reviewed mammograms from the first screening round of 46 healthy women, and of 74 women who had histologically proven breast cancers in the first screening round or later. The films were reviewed first as one-view screening and later as two-view screening. Fifty-one breast cancers were detected by at least one of the screeners on either one-view or two-view screening. The mean increase in sensitivity by using two views, instead of one, was 2%. The median of the proportional increase in detected cancers as the result of independent double reading was 14.5% with one-view screening and 12% with two-view screening. Two screeners using one-view screening detected about 10% more cancers than one screener using two-view screening.
五名经验丰富的筛查人员独立且盲法审查了46名健康女性首轮筛查的乳房X光片，以及74名在首轮筛查或之后经组织学证实患有乳腺癌的女性的乳房X光片。这些片子首先作为单视图筛查进行审查，之后作为双视图筛查进行审查。在单视图或双视图筛查中，至少有一名筛查人员检测出51例乳腺癌。使用双视图而非单视图筛查，敏感性平均提高了2%。单视图筛查时，独立双人阅片导致检测出的癌症比例增加的中位数为14.5%，双视图筛查时为12%。两名使用单视图筛查的筛查人员比一名使用双视图筛查的筛查人员多检测出约10%的癌症。
