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.
对1965年至1974年(含)期间在牛津地区出生的唇裂和/或腭裂患儿进行了检查,以寻找任何聚集倾向的证据。采用了诺克斯(1963年)、大卫和巴顿(1966年)以及史密斯和派克(1974年)所建议的方法。在空间或时间上均未发现明显的聚集现象。在1965年至1971年期间,孤立性腭裂在时空上有一些聚集迹象,但在1972年至1974年期间未再次出现。
