The Kaplan-Meier method, used for estimating survival rates from time-to-event data, indeed assumes that censored subjects (those who leave the study or are lost to follow-up before the event occurs) have the same survival prospects as those who continue to be observed. This assumption allows for the estimation of survival probabilities without the data from those censored subjects directly contributing to the event outcomes.
