A detailed analysis of suicide rates between 1960 and 1971 for England and Wales and for Scotland confirms that all age-sex subgroups have shown a marked decline in suicide due to domestic gas, corresponding in time to the fall in the CO content. After considering data on the effects of the International Classification of Diseases (ICD) Eighth Revision, accident mortality, some personal characteristics of coal gas suicides, and the use of coal gas in parasuicide it was concluded that a simple casual explantation was likely. Suicide due to non-gas methods has in general increased, markedly so in some groups. It was suggested that neither improved psychiatric services nor voluntary agencies could have produced such changes. The 'compensatory' trend of gas and non-gas suicide rates was indicated for certain age-sex subgroups. The continuing need for suicide research was pointed out, and questions were raised concerning the psychological meaning of the epidemiological data.
对1960年至1971年期间英格兰和威尔士以及苏格兰的自杀率进行的详细分析证实，所有年龄性别亚组因家用煤气导致的自杀率均显著下降，这与一氧化碳含量的下降在时间上相对应。在考虑了国际疾病分类（ICD）第八次修订的影响数据、意外死亡率、煤气自杀者的一些个人特征以及煤气在准自杀中的使用情况后，得出结论认为，可能存在一种简单的因果解释。非煤气自杀方式导致的自杀总体上有所增加，在某些群体中显著增加。有人认为，无论是改善精神科服务还是志愿机构都不可能产生这样的变化。某些年龄性别亚组显示出煤气和非煤气自杀率的“补偿性”趋势。指出了对自杀研究的持续需求，并就流行病学数据的心理意义提出了问题。
