How is censored cases handled in the KM
estimator? Let's consider the median survival time
in regards to censored cases.
Suppose in a study, the median survival time is
estimated to be 30 days, using the KM method.
Further, let's suppose there is just one censored
case before the median survival time. Now, if its
status is changed to be an event instead, will the
newly calculated median survival time be larger
than 30 or smaller? Explain your reasoning. Feel
free to use charts or graphs if necessary.
