Michael, you can also use -regsave- to save confidence intervals to a dataset. You can install -regsave- with the command -ssc install regsave, replace-
*****************************************
sysuse auto, clear
svyset rep78 [pw = turn]
svy, subpop(if foreign==0): total trunk
regsave, ci
list
******************************************
