Kaplan-Meier Survival Plot with Counting Method

Kaplan-Meier graphs are visual representations of survival data, commonly used in medical research and other fields dealing with time-to-event data. They illustrate the probability of an event (like death or disease recurrence) occurring over time, providing a clear picture of survival rates within a group. These graphs display survival curves, where the y-axis shows the proportion of subjects who survived past a certain point in time, and the x-axis represents time. Steps or drops in the curve indicate the occurrence of events. Kaplan-Meier curves are essential tools for comparing survival experiences between different groups, such as patients receiving various treatments or possessing different characteristics.
