| Abstract: |
| 采用1:4配比方法在某煤矿选取40例Ⅲ期尘肺现患病例及160名对照,运用多元Logistic回归分析对Ⅲ期尘肺易患因素进行了初步探讨。所得结果表明:结核感染及以圆型阴影为主的胸片表现与Ⅲ期尘肺有显著联系;开始接尘时间、工龄及工种等未作为显著因素引入回归方程。 |
| English Abstract: |
| Using 1:4 matched method, we have selected 40 cases of category Ⅲ pneumoconiosis and 160 controls in a coalmine, ani analyzed the factors which influenced the occurrence of category Ⅲpneumoconiosis by Multiple Logistic Regression Model. The results were as follows:Tuberculous infection and the type of radiographic appearence manifested mainly as small round opacities were positively correlated with the attack of category Ⅲ pneumoconiosis.The time of starting exposure to dust, the years and the kinds of work were not led into regression model as significant factors. |
