st: Twoway quadratic prediction plots with CIs in a multivariate regression setting

Hi,
I'd like to construct quadratic prediction plots with Cis based on a
multivariate regression, i.e. include additional regressors to the one
on which the quadratic fit is based on.
Essentially, I want to run the following regression:
/reg y c.age c.age#c.age i.male i.country_ind/ /num_hh_children income/
I'd like to have the prediction of the age polynomial based on the above
regression setting all other variables, respectively, to their base
level (factor variables) or zero if continuous.
Based on this prediction I need a plot similar to the one produced by
/qfitci/.
The Stata command /qfitci/ does only allow for one regressor that is
used to compute the quadratic prediction.
Does anyone have any suggestions?
