应用配对病例-对照研究调查了80例脑梗塞后的存活者,结果表明脑梗塞的发生与高血压、眼底异常、血糖增高、心电图异常等因素有明显关系。而与吸烟、饮酒、血脂不正常及阳性家族史等关系不明显。本文还对选出的四个危险因素进行了条件logistic多因素分析,结果表明各因素间存在协同作用。
The matched case-control study investigated 80 survivors after cerebral infarction and found that there was a clear relationship between the incidence of cerebral infarction and hypertension, fundus abnormalities, hyperglycemia, abnormal ECG and other factors. However, the relationship with smoking, drinking, dyslipidemia and positive family history is not obvious. In this paper, the conditional logistic multivariate analysis of the four selected risk factors was carried out. The results showed that there existed synergies among the four factors.
