    How come the upper bound for the final limit for the Kaplan Meier is 92
    The longest time we observe a patient for is 87 days so shouldn't this be the upper limit? I guess there are 92 days between the 1-Jun and 31-Aug but still not sure why this has been used, doesnt seem consistent with the course notes as no patient is actually observed for that length of time

    Hi

    It's possible this was a mistake in the Examiners Report. The graph below the table in the report looks like it runs to 87 rather than 92, which is the more logical end point.
