Baseline as confounding factor in logistic regression
Posted: Wed May 04, 2022 1:06 pm
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.
