I think you may want to take a look at receiver operating
characteristic or ROC analysis. This is a graphical way to represent
the trade-off between sensitivity and specificity between for two
tests. It creates a graph of the sensitivity versus 1-specificity. The
overall performance of a diagnostic test is captured by the area under
the ROC curve.

Stata has a set of 6 parametric and nonparametric ROC analysis
commands. You can learn more with -h roc-.
