You might try -cs- which will give you a risk ratio, as well as a risk difference (i.e., the ratio of the proportions, as well as the difference in proportions) and their confidence intervals.  Then you can choose how you want to express the result.

Dear Statalisters,
I ran a prtest to test the proportion of means between two groups. I think my 
problem is stating my result in a way that says for example: group A did X% 
better than group B. In other words how do I conclude that from my outcome?
