In England, Wales, and Scotland there is a strong association between mortality-rates and ABO blood-group distribution. It is suggested that some of the discrepancies in investigations of the relation between water hardness and mortality-rates from cardiovascular disease may be attributed to genetic influences.
在英格兰、威尔士和苏格兰,死亡率与ABO血型分布之间存在紧密关联。有人提出,关于水硬度与心血管疾病死亡率之间关系的调查中出现的一些差异,可能归因于基因影响。
