Final answer:
The Kaplan-Meier plot is a graphical representation of survival data used to estimate the probability of survival over time. It is commonly used in clinical trials and epidemiology to compare survival rates and analyze treatment outcomes.
Step-by-step explanation:
The Kaplan-Meier plot is a graphical representation of survival data in biology and medicine. It is used to estimate the probability of survival over time for a group of patients or individuals. The x-axis represents time, while the y-axis represents the proportion of individuals surviving at each time point.
The purpose of the Kaplan-Meier plot is to visualize and analyze the survival probabilities and compare them across different groups or treatments. It is commonly used in clinical trials, epidemiology, and studies involving time-to-event outcomes such as disease-free survival or overall survival.
For example, in cancer research, the Kaplan-Meier plot can be used to compare the survival rates of patients receiving different treatments or to identify factors that may affect the survival outcome.
