Hello,
I´m trying to obtain the geometric means and 95% CI with the eform option of regress. I´m working with logtransformed biomarkers and 3 eating groups. I have read the "Stata tip 1: The eform() option of regress" from Newson, 2003 but have problems working with it.
This is my syntax:
regress lnglucose w17age w17sex i.eatinggroup, noconstant eform(GM/Ratio) robust

 Robust
lnglucose  GM/Ratio Std. Err. t P>t [95% Conf. Interval]
+
w17age 1.001799 .0002353 7.65 0.000 1.001338 1.002261
w17sex  .7707707 .0082473 24.33 0.000 .7547574 .7871237

eatinggroup 
2  1.003426 .0122826 0.28 0.780 .9796131 1.027817
3  1.004425 .0145342 0.31 0.760 .9763085 1.033351

My question is, how do I obtain the geometric means of the 3 eating groups from the regress command? Is there another way?
thanks
