[Application of Joinpoint regression model in cancer epidemiological time trend analysis].

Joinpoint regression is a common method to investigate epidemiological time trend. Here we took cancer incidence trend analysis as an example to demonstrate the theory and practise of model from principles, steps, examples and attentions to give some references for following similar studies.Joinpoint回归模型分析是流行病学时间趋势分析的常用方法。本文以肿瘤发病时间趋势分析为例，从模型的基本原理、分析步骤、实例演示和注意事项等方面进行系统阐述，以期将模型的方法原理与操作实践有机结合，为读者开展类似的研究分析提供参考。.
