Dear STATAlister
it might be a minor question:
My understanding to KM survival model is to have the variable related
to the 'survival' event to be coded as (0: as nothing happened or 1:
as the event did happen)
For example if we are monitoring death: 1) died, 0) did not die.
I am assessing variable for sickness, to see if there is difference in
time to show between
option 1) patients who were sick before treatment and became sicker
after treatment
option 2) patients who were not sick before treatment but became
sicker after treatment
option3) And there are patients who did not show any sickness at all.
would i code them as follow:
option1 : code 1
option2: code 2
option3: code 0
Any tip?
Thank you and best regards
ziad
