Joining confidence intervals with a line

[Nazarius Mbona Tumwesigye]

i have plotted Confidence intervals (CIs) for prevalences of frequent alcohol consumption, obesity and hypertension by age group using the codes
ciplot freqalcohol hyper obese , by(agegrp) binomial jeffreys

what can i add to get lines that connect the CIs. i wish to see the three lines and their CIs?

ciplot is from SSC, as you are asked to explain. See also #2 of https://www.statalist.org/forums/for...ence-intervals

What would be the meaning or value of such lines?

Thanks
simply to show a trend over the age groups

[Nick Cox]

But that makes no sense with ciplot's design, as age groups would be separated, not juxtaposed.

As already suggested, just use statsby and design your own graph. Here is a silly but reproducible example.

sysuse auto, clear
clonevar rep78_2 = rep78 
recode rep78_2 1=2
statsby , by(rep78_2) clear : ci proportion foreign, jeffreys
twoway line mean rep78_2 || scatter mean rep78_2 || rcap ub lb rep78_2 , ///
legend(off) ytitle(Proportion foreign) note(Repair record 2 includes 1)
