Subject: Survival analysis
This a good question for experts in survival analysis and thanks in advance
for your answers.
I want to evalute if a variable that change during a time has or give a high
risk to died.
In this study we have followed up during one year to 100 TB persons, and in
each months we have evaluated their Auramine. This Auramine can chance
during the year. Some patients were detected like positives and not changed,
others changed of + to -, and also others changed of + to - and after to -.
I want to know if the persons who changed have more risk to get died.!!!
Thanks a lot,
