【正文】 的1268例初治肺結核病例進行為期3—6年的歷史前瞻性隊列隨訪分析，研究導致病情復發(fā)的危險因素及臨床意義。關鍵詞 結核，肺；復發(fā)危險因素；COX比例風險模型；歷史前瞻性研究Study of Prognostic Replase Risk Factors after First antituberculosis on Pulmonary Tuberculosis by COX Model.Abstract Object to study the prognostic replase risk factors after first antituberculosis on pulmonary tuberculosis and to establish the forecast model for the replase event at the same 1268 patients with pulmonary tuberculosis after first antituberculosis were followed by historial prospective study for 36 years,and the prognostic relapse risk factors were studied by COX proportional hazards our study showns that there are 9 independent variables(covariables) which could effect the replase rate of patients with pulmonary tuberculosis after first are age(X2) 、smoking(X4) 、nutrient condition(X5) 、regular cure(X9) 、discharge period of bacteria(X10),bine with diabetes(X11) 、residual fibrocavitary(X12) 、immune cure(X13) 、resistance drug(X14) ,our forecast model for the replase event is W=++++++. explained variation V2 is %,it showns that the forecase ability of the COX model is best for the replase this study suggests that the COX proportional hazards model is more effect in fitting the survival data and is much more sensible in analysis of prognostic risk factors after first antituberculosis on pulmonary tuberculosis than single variable analysis methods,we can use this COX model to estimate the probability of
