Sociodemographic characteristics are associated with participating in cancer screening and trials. We compared the characteristics of those responding with those not responding to a single invitation for prostate-specific antigen (PSA) testing for prostate cancer as part of the Cluster randomised triAl of PSA testing for Prostate cancer (CAP).
Age, rurality and deprivation among 197,763 men from 271 cluster-randomised primary care centres in the UK were compared between those responding (n = 90,300) and those not responding (n = 100,953) to a prostate cancer testing invitation.
There was little difference in age between responders and nonresponders. Responders were slightly more likely to come from urban rather than rural areas and were slightly less deprived than those who did not respond.
These data indicate similarities in age and only minor differences in deprivation and urban location between responders and nonresponders. These differences were smaller, but in the same direction as those observed in other screening trials.

社会人口统计学特征与参与癌症筛查及试验相关。作为前列腺癌前列腺特异性抗原（PSA）检测整群随机试验（CAP）的一部分，我们比较了对前列腺癌PSA检测单次邀请做出回应者与未回应者的特征。
在英国271个整群随机初级保健中心的197,763名男性中，比较了对前列腺癌检测邀请做出回应者（n = 90,300）和未回应者（n = 100,953）的年龄、居住在农村还是城市以及贫困程度。
回应者与未回应者的年龄差异不大。回应者来自城市地区而非农村地区的可能性略高，且贫困程度略低于未回应者。
这些数据表明，回应者与未回应者在年龄上相似，在贫困程度和城市居住地点上仅有微小差异。这些差异较小，但与其他筛查试验中观察到的差异方向相同。
