Abstract

Eighteen infants with neural tube defects occurring in 979 births over five years in a small Wiltshire town were investigated for evidence of spatial epidemicity. Applying a method not used previously in the study of these defects, clustering was confirmed, a critical distance between cases of up to 100 metres giving a highly significant result (P = 0·001), and with one exception the observed number of pairs significantly exceeds the expected number (P < 0·01) even up to 1,000 metres.

摘要

在威尔特郡一个小镇的五年间,979例出生婴儿中有18例患有神经管缺陷,对这些病例进行了空间流行性证据调查。采用一种此前未用于此类缺陷研究的方法,证实了病例聚集现象,病例之间高达100米的临界距离得出了高度显著的结果(P = 0·001),并且除了一个例外,即使距离达到1000米,观察到的病例对数量也显著超过预期数量(P < 0·01)。
