rajesh:
One way I like is to add confidence intervals around the estimates. I you
want to do that than you
could have a look at Roger Newson's -eclplot- and other associated commands.
Roger Newson has a
prepublication draft of his article in Stata Journal on how to use these
programs on his website.
Another thing you could do is make a line graph and graph a second line on
top for only the
significant results which is a lot thicker, or do a scatter plot where you
plot the
non-significant with open symbols and the significant ones with closed
symbols. I've shown that in
the example below.

Maarten
