Subject   st: statistical test and sensitivity analysis for matched pairs with censoring

Dear all,
I am using Stata11 and working on the observational data.
I produced the one-to-one matched pairs using PSMATCH2 to compare the
treatment A with B in terms of maintenance effect.
The primary outcome is the time to recurrence of the disease.
There are two questions I would like to ask you.
1) What is the appropriate statistical test in this situation? RF.Woolson
seems to recommend censored-data version of signed rank test. But I have no
idea how we can do it on Stata. 
2) How to perform sensitivity analysis to determine the magnitude of hidden
bias in this case?

I wonder if you could help me to know the way to operate Stata for these
purpose.
