Kaplan-Meier curve

It is used to illustrate the probability of survival over time for a group of individuals

In this we have x-axis (length of time) and y-axis (event probability)

x-axis (length of time): represent the time interval during the events (moths, years)

y-axis (event probability): probability of an event occurring over time (ex. Mortality, disease reoccurrence etc.)

survival probability

it represents the probability that an individual or a group of individuals will survive up to a specific point if time

Survival probability = 1- event probability
