Hello,
I have a dataset with cognitive ability score measured at two time points. I am interested in running a regression model that would show me the changes in cognitive abilities from 30 day to 1 year based on a number of other variables (demographics, pain score, etc.). For example, I would like to know what is the average change in cognitive ability score for +1 year in age. I am using Stata 16.0 and am grateful for any help with coding.

Katie
