Hello,
Here are the details.
I run a logistic that gives me the ORs (not the betas).
When I try to get the conf interval and p-value, they do not appear. I also tried running an OLS regression and the results are the same. I am stuck in the syntax.
I am using the latest version of outreg and I read the help file - realizing that a lot is possible using outreg. However, I am not getting the basic syntax. Maybe someone has used this version of outreg and has some hints about how to get the output with OR, p-value and conf interval? I also would like to report the value of the constant.

Thanks.

It may be you have a syntax error, but -outreg- has a zillion options so if so it isn't obvious to me. In any event, could you be more specific? What do you mean, "it did not work?" Are you getting an error message, or are you just not getting things printed out that you would like, or what? It would help to show the command you typed before outreg, along with the message or output you got immediately afterwards. I might also drop the "using results" temporarily so the output is printed to your screen.
... and if you're running exactly this from a do-file:
outreg using results, b ci p replace ///

Then it may not work because of the /// at the end of the line (which tells Stata that the command continues on the next line - so either the /// shouldn't be there or you haven't shown us the entire command).

Also, -outreg- is not part of Stata - it's a user-written command from SSC. You should mention this in your post and tell us which version you're running (-which outreg-)
