I code them as event=did not experience event, and set their second date as date study ended/final data collection.

I would think you'd bias the sample otherwise.

Best,

Subject: question about right censoring in survival analysis

Hi there:

The definition of right-censoring is: The subjects whose Event time is longer than the study terminate time, without knowing when it is. My question is if one survives through the whole study period and not sure whether whether an event will happen or not, how are we going to treat him?
I don't think they are right censored. Then are they going to be deleted from the study?

Thank you!
