Immortal-time bias in older vs younger age groups: a simulation study with application to a population-based cohort of patients with colon cancer

BACKGROUND: In observational studies, the risk of immortal-time bias (ITB) increases with the likelihood of early death, itself increasing with age. We investigated how age impacts the magnitude of ITB when estimating the effect of surgery on 1-year overall survival (OS) in patients with Stage IV co...
