In this question, they asked about a Kaplan-Meirfirst, we have to discuss what is Kaplan-Meir?The Kaplan-Meier method is a statistical approach used to estimate the survival function of a population based on time-to-event data. It is commonly used in medical research and other fields to analyze and compare the survival rates of different groups.The method involves calculating the probability of survival at each time point based on the number of participants at risk of the event at that time and the number of events that have occurred up to that point. These probabilities are then multiplied together to obtain the overall survival probability for the entire follow-up period.
