Difference two paired proportions

Hello,

I have a binary variable (yes/no) and two measuring time (T1 and T2). Thus data are not independant.

I would like to calculate the difference (in percentage) between the proportion of "yes" at T1 and the proportion of "yes" at T2. Moreover i need to calculate the confidence interval of this difference.

I thought it was possible using proc freq (as paired ttest) but i wasn't successufll at getting it to work.

Hoping that you can help me.

Thank you.
