Dear Stata users,

I have calculated mean changes in eGFR in 2 groups using mixed model.

Group 1 mean changes in eGFR per year =-1.29
Group 2 mean changes in eGFR per year =-1.86


Now I am trying to compare mean changes in eGFR of groups 1 and 2 for statistical significance.
Is there a reasonably straightforward way to calculate a p-value for this, from the data provided above.



Thank you so much.
