Survival Analysis and Kaplan-Meier Curves

Quick fact

The Kaplan-Meier curve gracefully handles the missing information from censored patients by assuming that censored patients have the same future survival prospects as those still under observation—a key assumption that shapes all survival estimates.

Why this is interesting

Imagine a clinical trial where some patients are still alive at the end of the study—their survival times are incomplete. How can we still estimate survival probabilities accurately when we don't know when those patients will eventually die?
