Note also, lead time bias can only change the statistics for the period of time the patient is still alive. Once the patient dies, the lead time no longer matters. Unless the study is conducted over a period of time that is not long compared to the lead time differential, there is little effect on the result.
I have no idea what the **** this is supposed to mean. Maybe you should try to figure it out. It is written in Canadian-compatible English, with well-formed sentence structure, a premise, supporting content, and a conclusion.
