Dear all,
I have a question about how to show my new data post-age correction.
So imagine, protein A is different between group 1, 2 and 3. However these groups differ in age, so we have to perform age corrections (I do this with GLM--> univariate --> covariate: age)
now my question is how to depict the data after this age correction in a box plot? so one of the methods I was considering was to save: unstanderdized predicte values, and then do the box plot with the new saved data. However i am not certain if this method is correct, and if not, how should I perform this task?

Thank you in advanced

Kind regards
Arjan
