st: using foreach in regression models

Hi all,
I am running a number of logistic regression models (Stata 11.2), using the same dependant variable, but cycling through a number of independent variables to obtain 'unadjusted' regressions like such:
xi: logit treatmentinsccnetre2 i.agegrp, iterate(10) or
xi: logit treatmentinsccnetre2 i.NRCENT, iterate(10) or
xi: logit treatmentinsccnetre2 i.id07, iterate(10) or
xi: logit treatmentinsccnetre2 i.site_4, iterate(10) or
I can condense this down to the following
foreach v of varlist agegrp id07 NRCENT site_4 {
xi: logit treatmentinsccnetre2 i.`v', iterate(10) or
}
This is fine, however, I also do want to run the analysis by introducing a range of other variables in order to 'adjust' for their effect. The list of variables will always be the same, but although the list is the same, some variables move around the list - if they are the variable of interest i.e:
xi: logit treatmentinsccnetre2 i.agegrp i.NRCENT i.site_4 i.sex i.id07 i.yydx, iterate(10) or
xi: logit treatmentinsccnetre2 i.NRCENT i.site_4 i.sex i.agegrp i.id07 i.yydx, iterate(10) or
xi: logit treatmentinsccnetre2 i.id07 i.NRCENT i.site_4 i.sex i.agegrp i.yydx, iterate(10) or
xi: logit treatmentinsccnetre2 i.site_4 i.sex i.agegrp i.id07 i.NRCENT i.yydx, iterate(10) or
What I would like to do is use the loop I employ for the unadjusted model, but be able to use something like `v' in order to condense the code from the above.
Any ideas?
Best wishes
Tim
