In the Frederiksberg screening program from 1962 to 1972 invasive carcinoma, carcinoma in situ or severe dysplasia of the cervix were found in 155 previously unscreened women. In previously screened women 137 lesions were later elucidated, 53 of these at rescreening. If a failure of method of 10 per cent is anticipated, 21 cases were probably missed due to the method chosen. Patient failure was noted in six cases and two cases were missed by insufficient follow-up by the doctor. The importance of a high participation rate is emphasized. The cytologist's error was 19 per cent. Sixty-four cases were estimated to represent new cases developed between screenings. A reduction of cytologist's error is assumed to be the most accessible way of improving screening results.
在1962年至1972年的腓特烈斯贝格筛查项目中，155名此前未接受过筛查的女性被发现患有宫颈浸润癌、原位癌或重度发育异常。在之前接受过筛查的女性中，后来又查出了137处病变，其中53处是在复查时发现的。如果预计筛查方法的漏诊率为10%，那么由于所选方法，可能有21例被漏诊。有6例出现患者未配合的情况，有2例因医生随访不足而漏诊。强调了高参与率的重要性。细胞学医生的误诊率为19%。估计有64例代表筛查期间出现的新病例。减少细胞学医生的误诊被认为是改善筛查结果最可行的方法。
