About Kaplan-Meier
Kaplan-Meier estimates survival probability over time, handling censored observations.
Censoring: When the event is not observed (lost to follow-up, study ends).
Greenwood's formula: Used to calculate SE for confidence intervals.
Median survival: Time when survival probability reaches 50%.
