本文报告的是用COX回归方法,对Ⅲ期煤工尘肺发病影响因素的分析结果。发现,诊断Ⅲ期前合并肺结核明显增加发生Ⅲ期煤工尘肺的危险性,而首次粉尘暴露-诊断Ⅰ期时间则与发生Ⅲ期煤工尘肺的危险性呈负相关。
This paper reports the results of the analysis of the influencing factors of stage Ⅲ coal worker’s pneumoconiosis using COX regression method. Found that the diagnosis of pre-stage Ⅲ combined tuberculosis significantly increased the risk of occurrence of phase Ⅲ coal workers pneumoconiosis, and the first dust exposure - the diagnosis of stage Ⅰ with the occurrence of phase Ⅲ coal workers pneumoconiosis risk was inversely correlated.
