Kaplan-Meier survival data can be used as input data to a Markov model. This article and its associated model show two methods to generate transition probabilities from Kaplan-Meier survival data.

- Represent the empirical survival data with a parametric distribution.
- Use the empirical data directly, by creating a Cumulative Density Function.

GSHPChinaIt's a great an example, for more thing, in three state markov mode （Progression free state, Progression state , Death）, PFS curves calculate which two state transition probability? So as to OS ?
