Observation of numerous survical surves connecting the survival rates with time usually expressed in yearly intervals has permited the elaboration of patterns describing survival probability in terms of time. Gross survival patterns, from which the most utilized is the exponential pattern, must be distinguished from comparative surival patterns that debouch into the recovery probleme. Their interest is to caracterize survival for a group of patients with the assistance of a limited number of values (three at most). From that, follow their practical applications: comparison between several groups that may differ either from the characteristics of the discase or from the received treatments and from the vital future forecasting, either on one group's level, or for an individual.
观察大量将生存率与时间（通常以年为间隔表示）联系起来的生存曲线，使得能够制定出根据时间描述生存概率的模式。必须将总体生存模式（其中最常用的是指数模式）与涉及恢复问题的比较生存模式区分开来。它们的作用是借助有限数量的值（最多三个）来描述一组患者的生存情况。由此产生了它们的实际应用：在几个可能因疾病特征、接受的治疗或重要的未来预测而不同的组之间进行比较，无论是在一组的层面上，还是针对个体。
