Abstract
Children with cleft lip and/or palate born during the period 1965-74 inclusive in the Oxford area were examined for evidence of any tendency for clustering. The methods suggested by Knox (1963), David and Barton (1966), and Smith and Pike (1974) were used. No clustering was evident in space or in time. There was some indication of clustering in space-time for isolated cleft palate during the period 1965-71, but this was not repeated during 1972-74.
在1965年至1974年期间出生在牛津地区的唇裂和/或腭裂儿童进行了检查，以寻找任何聚类倾向的证据。本文采用了Knox(1963)、David and Barton(1966)和Smith and Pike(1974)提出的方法。在空间和时间上都没有明显的聚类。孤立性腭裂在1965-71年间有时空聚类的迹象，但在1972-74年间没有重复。
