    KM curve




    Hi all,
    If I have a KM curve (survival vs years) and I have the number at risk each year (as well as hazard ratio for death over a median follow up - can I calculate the actual number of events or is it impossible since no data on drop outs or end of follow up?
    thank you

    Where is this data coming from, a publication? If so, can you reference it.

    Re: KM curve

    Not sure if we can actually reconstruct the number of events from the published survival curves. However, a lot of things can be extracted.
    These papers may be helpful , although they don't answer your questions specifically.

    Oh Thou Perelman! Poincare's was for you and Riemann's is for me.
