| 摘 要： | 目的以神经胶质瘤为例阐述3种生存分析参数模型拟合方法的应用.方法用危险率图、生存率图及数值法三种方法对患者术后生存时间的分布进行拟合,并用C*检验进一步作假设检验.结果神经胶质瘤患者术后生存时间用三种方法拟合后,皆显示患者术后生存时间服从威布尔分布;经检验P＞0.2,亦说明威布尔参数模型可用于患者预后因素的研究.结论临床资料在拟合分析后,应用其特定的参数模型进行生存分析. |
| 关 键 词： | 神经胶质瘤 拟合优度 威布尔分布 |

| Abstract: | Objective To introduce three model-fit methods of survival analysis and its' use. Methods this research applies two graph methods and numerical method to fit the type of probability distribution of patient's postoperative survival time; uses C * test to do hypothesis testing.Results three results all show that postoperative survival time with glioma follows Weibull distribution; the result of C * test also shows Weibull regression model can be used to study patients' postoperative prognose factors(P>0.2).Conclusion After fitting distribution of clinical data, we should use its' specifical parameter to analyze patients' postoperative survival time. |
| Keywords: | Glioma Goodness of fit Weibull distribution |
