相对危险度和归属危险度是流行病学研究中衡量一种可疑因素是否与某病的致病有联系的统计指标。以这两种指标的数值大小,来表明这一可疑因素对某病的发生具有何种影响及影响的大小。也可以说它们是用来表明接触这一因素而产生疾病的危险程度。 现以职业性接触二硫化碳毒物与发生心肌梗死的关系为例,说明相对危险度和归属危险度两个指标的意义。表1是接触二硫化碳粘胶
Relative risk and risk of attribution are the statistical indicators used in epidemiological studies to measure whether a suspicious factor is related to the pathogenicity of a disease. The numerical size of these two indicators to indicate the suspicious factors on the incidence of a disease have an impact and the size of the impact. It can also be said that they are used to indicate the degree of risk of developing a disease when exposed to this factor. Now occupational exposure to carbon disulfide poisoning and the occurrence of myocardial infarction as an example, indicating the relative risk and attribution of the significance of the two indicators. Table 1 is the contact with carbon disulfide adhesive
