You will have to consider the appearance of the plot. I suggest that you put the RRRs for each outcome as separate 'studies' into a datafile, together with their confidence intervals. 


Your datafile should look like

input e_group outcome rrr lcl ucl



Your study ID variable is actually the name of the ethnic group (e_group). 
The outcome variable identifies the outcome associated with the RRR.

You can then use -by(outcome)- to display the RRRs for each outcome with the ethnic groups shown one under the other. 


Or at least, this is a starting point.
