Baseline as confounding factor in logistic regression

Post by viniciusnagy »

Hello guys

I want to know if swallowing complaints (continuous) can predict dynapenia (binary) in an 8-year follow-up cohort.

Classically, I should exclude participants with dynapenia at baseline and estimate the coefficients for follow-up, correct?

The problem is that dynapenia is a modifiable condition, which means that the presence of dynapenia at baseline will not necessarily result in dynapenia at follow-up.

Given this, would it be acceptable to consider dynapenia at follow-up as dependent variable, and dynapenia at baseline as confounding factor (covariate)?

Thanks in advance.
