Is there a way to compare survival of paired samples (paired samples variant of the logrank test/Cox regression)?
I would like to assess difference in survival of the "same" cohort classified by two different classifications of disease. Most of patients with the disease would be the same in compared groups, but some will be included or excluded due to the difference in classification criteria. Would standard log-rank test be appropriate? Is there a method that would account for shared patients?
